I want to personally say THANKYOU, after watching your idle reset video, my foxbody has never run this good, this smooth, this lady like.......I’m in love once again with my coupe......thank you sir for your help posting up this video!!!!! Greatly appreciate car people like you....! Thanks again and keep the videos coming in!!!!
@@BREW2LFOXBODY i have a 1987 mustang gt Anderson n41 camshaft afr heads 24lbs injectors 24lb mass air meter was having idle issue it's been tuned guy told me i needed an idle air control adjuster i put that on and new IAC haven a hard time to adjust ilde
Thank you from one veteran Foxbody owner to another. Proof that even though I've been around these cars for years...There's still simple things that will help make my Foxbody ownership more enjoyable.
That's the thing I love about these cars, It's one of the few cars left that doesn't require a custom tune for most things and can be worked on in your own driveway. Thanks for watching!

Chris aka Enlightened Eyes of the Lions Pride thanks brother! I guess it's our job to pass along the our passion for these cars and hopefully it rubs off on the younger generation.
Got to tell you brew2l you are the man. Just got thru a rebuilt motor and a trick flow top end kit with the stage 2 cam and you saved me with the idle. Idled good but coming to a stop or coming down off a rev it would stall every time. Did the base idle reset and it fixed the problem. Thank you for all the help you have provided with your channel. Was getting very aggravating restarting it at every red light. Next move is removing those isolators on the front springs. Just need that extra 1/4” drop. I’ll be referring to ur video for that too. 👍👍🇺🇸🇺🇸
Thank you! I've been having so much trouble with my tps and my car running horrible. I followed your instructions step by step, starting with adjusting my timing. My car has never ran so good! Thank you!
No lie brother I thought this wouldn’t help. I’ve been chasing this dam problem for a minute. You weren’t lying. I felt the difference right away. Thanks for this video
i spent the past several months fully rebuilding the engine in a 1989 f150, every single bearing, gasket, seal etc. all brand new, put a mustang intake manifold on it, longtube headers, made a custom full exhaust and intake, put it all back together and all the sudden its throwing 10 ecu codes and idles at 3000rpm. i spent a month just trying to figure out why the hell it doesnt just run the way it did. changed the distributor back a tooth which retarded the timing too much, GLOWING HEADERS lmao that was terrifying.... didnt even know that could happen but i set the timing back to 10 degrees and the idle went right back up with it. i didnt even know you COULD adjust the tps. after seeing this video i cant wait to go back to my garage and set all this stuff up and get this thing running perfectly the way it should. thank you so much for this video man i havent seen this information anywhere else in weeks of searching.
This video needs to always come in first place on google for idle resets. My 88 Cougar runs like its from the factory now. We need to never lose this video.
Thank you for your most informative video. The base idle was WAY off 2 turns. It just barely idled when I pulled the idle air control I adjusted the TPS as mentioned and that was off as well. Plugged it back it and I have my idle back and NO MORE stumbling off idel As he says do the base idle adjustment Its worth it!!! THANK YOU!!!!!!!!
Holy shit! I had cam, rocker arms , valve springs put in my car and the guy adjusted timing well but my car would cut off at stops or sharp turns after it got to running temp, I did the base idle reset this morning and took her for a 20 minute ride after that and she’s purring ! Thanks Brew2L!
Nice to see someone playing with that idle set screw.....I had always heard never to mess with it, but now I know the proper way to set it as well as the tps.....thanks again
I have been playing with these cars since new. This video gave the most concise description of how to CORRECTLY set idle and the TPS. Great stuff! Subscribe!
Let me know tell you that I’ve been going crazy trying to figure out the idle with a recently built stroker with a healthy cam. I followed your instructions and the damn thing stabilized within a couple of minutes! It has never idled this good. However, every time I start the engine it hunts for idle for some 10-20 seconds but it stabilizes eventually. I don’t know why it happens. I’m grateful for your effort sharing this video. Thank you!!
I think that's the iac doing it's job. Mine does the same depending on how cold it is. It will idlle up high at startup and stabilize. If the engine is warm it goes right to normal idle.
Thanks a ton man!! Got an 89 Town Car that’s been acting a bit funny. Love learning about it all and doing all the work myself. It’s a car I want for life!
This process will make any combo run smooth. Me and my buddy had high compression, head cam intake setups and could both take off, from choppin idle, no bucking. GOOD VIDEO!
Got a 91 lx vert recently, drove her back home 2.5 hrs no problem, idle started surging a tiny bit maybe 250rpm fluctuations, drove for a few days and suddenly got a 2k rpm idle, tested IAC and TPS all was good, but didn’t remove IAC to see if I could blow air through it, removed IAC and could blow air through easily, replaced IAC and idle went back down to an 850-1000rpm surge, she would start and idle great until I hit the gas then start surging, decided I’d just replace the TPS and do another base idle reset, perfect and steady idle!!! I’d like to note that the breather port on the valve cover was plugged with a cap as well as the one on throttle body, I installed a hose between the two and noticed my gas pedal is no longer stiff from off idle. I’m guessing the TB vacuum was holding it closed just just enough to where I couldn’t ease on the pedal, helped a huge amount with 1st/2nd gear slow speed control and bucking. Thanks to you I had a great platform of knowledge to work from, and with that my car is running absolutely beautiful now.✌🏼
Good day sir I just picked a 90 lx and found that when car is cold is surges and after it warms up it idles at about 1k and never idles below that where do you think I should start any help would be appreciated and I love the channel good info as always!
How ya been man. I have Missed a lot of videos. Been crazy here, my wife has been in and out of the hospital a lot. I bought a 94 GT , drove it home and need to watch the missed Videos.
I appreciate this video fixed my issues with surging idle. I went through everything n thought I had a vacuum leak or electrical issue. Vacuum lines where orig n the salt n paper shakers 10 pin connectors are very problematic but this was my fix thankyou. Also got rid of the 10 pin connectors n all new vac lines runs great all stock but o/r hpipe n the old bumped timing lol. #foxbody.👍👍
I had same issues and might have a vaccum leak plus mine still has all that smog junk on it, ive forgotten so much of this stuff, i remember filing the tps so i could adjust it by the screws 20 years ago but the other things i dont remember until watching these videos then it sparks the memory of working on my 86gt over 20 years ago recently got an 88 lx and mine is running like shit until warm up and raggedy then
Your videos are great and easy to understand.thnks for that.i do step by step what are u doing but my question is when i unplug the iac valve the enigine check light appears.does it make any diffrence in reset procedure?becouse it didnt went out until moving the car? thnks for nice videos again.
The exact video I’ve been looking for my B303 idle has been all over the place I’m guaranteeing this is going to fix it I’m gonna look into it soon thanks !!
Great video! I have a bunch of new parts to install and this will help refresh my memory when it comes time to reset everything. I should remember all this stuff, but I got hurt pretty bad in a work accident several years ago and it has left me disabled and unable to do much of anything for a number of years and that old saying "use it or lose it" sure does apply.
Robert G sorry about your accident... but seems like you are still pushing forward and enjoying life. Nothing wrong with a little refresher. Thanks as always for your support.
I just added a Gt40 tubular intake too my 90 5.0 and it runs great driving down the road but when stopping the idle will drop low enough to kill the motor sometimes or idle jumps and before the intake swap it was perfect. What do I need to check and how to fix the idle drop issue. Will this help me possibly what your doing in the video? Thx
I have a 89 5.0, sat for 13yrs, I have replaced the entire fuel system including 22lb injectors.. new TPS, EGR, MAF, BAP, vacuum lines, smoked it and fixed all leaks and still will not run right. New O2 sensors and still getting code 41 & 91…reflashed PCM and made sure the Orange ground wire for o2 sensors is grounded good with no change…I would like to talk to you about what else I could do to fix this issue.. Thank you
Your videos are great and easy to understand. Question do you think a base reset will fix my stalling at slow speeds / stops plus running rich? I changed plugs and cleaned cap and rotor so far. Old plugs were terrible. No problems with cap/rotor and still runs rough but fine under load. It is a 89 5.0 GT motor 5 speed in a 50 Ford. Pretty bad ass. A cool fox motor in a shoebox. Keep up the great channel.
@@BREW2LFOXBODY Thanks man. I put over 1K on it this past year and the stalling and misfires / running rich got worse. Forgot to mention plug wires are good and do not sense any vacuum leaks. Was thinking of changing TFI module or replacing the distributor as the pickup coil is known to fail with these symptoms. Thanks for the quick response and will start with base idle reset.
@@BREW2LFOXBODY Attempted to set the timing today after I warmed up the car. Problem was my battery is in the trunk and with my jumper cable attached to my timing gun still was not able to reach engine bay to check timing. Anyway when I removed the spout plug from the distributor after car was warmed up it would barely idle at all. I could tell that this may be one of the issues as to why it may be running too rich and the plugs I pulled looked like crap as they were very black. I can only assume that till I get a gun on it. I think the timing is set way to low and whoever worked on it before me compensated by adjusting the idle to make it run fairly well. Would mention that it idles decent when spout plug is in it but I can here it surging when warmed up. I think when I do the base idle reset that should fix the problems of it running rich / backfiring a bit. Not sure it will help with the stalling. Thanks again for your quick feedback and my filter looks clean and not plugged.
My car was running pretty good until the ECU burned for some reason I replaced it with the same A9P so I went ahead double checked timing 14 degrees rpm 650 and I set the tps at .97 it feels the same only difference is when I take off is easier hard to stall now and then it feels like it has better throttle respond thanks u also had a question what did you use for your dash lights their brighter
Hey BREW2L would this apply to a 94 ford Bronco with a stock 302 5.0 engine? and would I have to move my idle screw. I know for a fact that the idle screw is still set from factory it's never been moved. thanks brother for the help. GREAT VIDEO.
Hi there, i have followed every step n still cant get it right,i have a 91 Lincoln mark vii that came with the same 5.0HO motor as the Mustang,,for some reason my car never stall with aic unplugged,no matter how much i play with the throtle screw to set the idle to the lowrest car still idles around 600 rpm with iac plug disconected,any ideas? Great video by the way
Hey man I’m hoping you can help me! First off, thank you. This really helped my cars idle as well as mine has an ecam . The issue I am having is when I turn the ac on. If I don’t idle it up some with the idle screw sometimes it will surge and die. Also, isn’t the iac supposed to increase the rpm when the ac is kicked on? My rpm’s drop when the ac is on not increased. Thought was a voltage issue. Upgraded to 130 amp sve alternator and still does it. No vacuum leaks. Thanks for any help.
I had a question for you. So i messed with my tps sensor awhile back will that make my fox overheat if i didnt adjust it properly.? Because I'm trying to chase down a overheat issue, so far i did a new radiator water pump and thermostat and I have a vacuum refiller cornwell vacuum assist cooling system refiller Which also is basically A pressure tester as well because you pull a vacuum. I'm just trying to see where you think. I need to go from here because you seem to know these the best I think
Love the video helped out a lot my foxbody idels great of the start but when she warms up it likes to cut out at stop lights do u have any suggestions I'm thinking bumb the idel up a bit but have u ran in to this problem before. Love your car looks great
Glad the video helped some. You’re probably right the idle needs to be brought back up. Just keep a check on the tps voltage to make sure it’s still within range after your adjustments. 👍
Ive been doing mine by some instructions online that didn't require unplugging the clip from the distributor. I'm gonna try your technique tomorrow. My 88 gt randomly idles super low when I come to a stop. But when I accelerate, it doesn't hesitate or anything, it just takes off without any issues. Unfortunately my tachometer doesnt work so I can't see physically what the rpms are at so I'm gonna try it by ear. Hopefully I can get it to run better tomorrow. Thanks for the video!
Great video, however this seems not to fix my issue on my 86 I just bought.. it runs perfect until the engine hits about 130 degreee then starts surging badly. Cleaned the iac, theres no vacuum leaks did a smoke test,, cant figure it out for anything..any idea? Thanks
Question so I can start my car with out that plug in it. I get my tps to about .96. Then I plug that thing back in and let it run. When I go to check the final tps it’s 1.111 ish. Do I adjust the tps or ideal? To bring it back down?
BREW2L, great video.....I recently swapped heads to Aluminum and added pro form 1.6 rr but the other mods below were pre-existing without this issue.When driving the car the last couple trips around the block I have noticed the rpm drops down to 500 or lower when slowing to a stop and the tranny is in neutral. If I down shift to a stop it seems to be fine. The car even shut off once but started back up easily. The car idles great after base idle reset which I perform basically just like you do here except about 8-900 RPM final setting. The car idles with/without the IAC plugged in. RFP surges a little upon start (maybe for 15 seconds or so) then levels out.Car does not have any smog or egr to speak of. Only vacuum lines are intake to FPR, intake to PCV and intake to vac tree. I don't see that any are leaking.Thank you for your input.Mods:1990 GT, gt40x heads, 1.6rr, recently added, TFS1 cam, pro flo 75mm MAF, CAI, BBK 75m TB and 19lb injectors, 1-5/8 shorty's, x pipes, bullets with dumps.
90Fox thanks for your input on the base idle reset. As you already know these things are temperamental. I have found that the 2 minute load run during the reset is about the most important part of the process. I have in the past turned the steering wheel to full lock along with all other accessories on. That way no NEW unexpected load shows up and freaks the car out. I know your issue isn't really a load problem but it might not hurt to try that along with a lower idle without the IAC plugged in. Everytime I bump the idle up to the point it runs smooth without the IAC plugged in the car seems to run worse afterwards. From my understanding the IAC needs to be the only thing correcting the idle. Thanks for watching and sharing your input.
My car idles fine with or without iac plugged in also. It keeps throwing code 54 act. I changed the sensor and it still shows it. What ohm or volt should it show when testing? Thanks
Hey is the process the same for a 94 sn95 5.0? Im having some issues at idle and want to go through all this, but idk how much has changed between the foxbody and the sn95..appreciate your feedback
question for you: Car is having a hard time starting. It turns over and will sometimes crank but not all the time. I have done the trick of priming the fuel pump, turn almost to crank three or four times then crank, it does not seem to help. Car runs great when it cranks. What do you and your community think: Fuel Pump, Fuel Filter, some kind of electrical issue...???
Thanks man this video helps out a lot, I’m at this point trying to set my idle and adjust tps since I swapped tps sensors. I got a new build and my car wouldn’t start. Due to a bad tps.
I have an 86 GT Foxbody with 5.0 HO engine. Lately when I start the car (hot or cold), the engine idles at about 3000 for about 3-5 seconds and then calms down. What could be causing this? I have checked everything, so I’m getting ready to replace my ACT, coolant temp sensor, EGR valve and both O2 sensors. BTW, the car has 396,000 miles on it.
Just some cheap ones from Amazon. Search my channel I have a video with links to them. But I honestly can’t remover the title to the video right off hand
just got doing this to my beater, cleaned it up a bit but still need to tweak it.. unknown cam set up with bbk junk t-body and a stripped allen set screw way out of adjustment tps over 1.4. lucky I had a accufab in the garage.
that would take too long.... no idea who built this, and its staying a beater so only getting used parts thrown a it. has an eagle 347 kit and all the bolt on crap, decent upr suspension, cobra 5 lug swap, all the bells and whistles except they used e7 heads on it and the body is ruff. has some decent parts on it but damn its like they threw darts at the summit catalog total mismatch.. will be a good donor car if I can find another decent coupe.
Can I just pierce the cables from the tps? No luck sticking them at the connection I get no reading, (key on and running) . Would there be a problem if I pierced them and leave a little hole on the cable?
you should of showed how to install the volt meter and what setting to put it on. mine wont read .98 no matter what wire i put it in ect best i can get is .30s-.45 ish it wont read any higher no matter what i do, it runs fine so i just said screw it and left it be
Hoping you can help, what do you recommend to do when I disconnect the Idle Air Controller the car stalls? I've got a good ide and correct TPS but am trying to diagnose a rich fuel mixture...
I've adjusted the screw to close and opened 4 revolutions (one turn at a time). Car still stalling. Return to original screw setting, plug back in and starts and idles fine with TPS 0.97
Hey, I think I have a stock 93 gt with a warm air intake, every time I start the car cold it fires right up, rev's up a little and dies. Re-start it and it's fine. Any ideas? My car sits a lot.... I leave the battery unhooked so maybe I need to do this procedure every time?
Brew I have a 1990 Mustang GT and I’m having all kinds of problems start the car and it runs fine for a while then shut it down and try to restart but it won’t restart unless I depress the gas pedal to the floor. Then it runs for a while then starts to surge and will shut down. Please help
Man I just installed a BBK 70 mm on my 92 and I’m having all kinds of issues. I’ve tried everything here, but it’s popping like crazy, idles rough, and revs by itself. Any ideas?
@@BREW2LFOXBODY just going back through the library of videos you have. Having some idle issues with my b cam. But ill get it. Also Mr. Fusiom I made works excellent.
I tried to check voltage, and all 3 wires show 5.02 volts with engine off,key on. Why is it so high? Has new sparkplugs right now. Original wires,and unsure about timing .
I'm hoping you can help.. In the process of doing the base isle reset, I can't get my tps above .68 volts. I slotted the screw holes as far as I could and still won't go over .68. Any ideas what I can do?? Thanks in advance
I've had all this set up how you did yours once cars gets to Temps after 25 min of driving it likes to jump to 1800 rpm and hot start only starts to the floor and has a weak idle down to 1800 any ideas?
my 87 5.0 revs on its own , this happens randomly. I was told its the idle air control. should I replace this or is it the tps sensor. hope you can help
Hey buddy can you tell me the cheapest we to do a 5 lug and dis break conversion on a 1988 convertible I just bought one did a couple on builts on old caddies but never a muscle car any info will be greatly appreciated thanks
going to do this today, question about my 91 mustang 5.0 AOD i was driving it on the highway after a new stall converter, plugs rotor and cap fuel filter. i gave it alittle bit while driving and it felt fine all the way up to about 85-90 mph and didnt go any further. almost as if it had some sort of governer. any ideas? still havent done the base idle reset yet

Thanks a million for this. My car is running great.
You’re welcome 👍 Hope the video helped!
The exact video I’ve been looking for my B303 idle has been all over the place I’m guaranteeing this is going to fix it I’m gonna look into it soon thanks !!
shelby 4485 hope it helps! Thanks for watching
Thanks for the video. Definitely saving it for future reference when I need to reset mine.
Awesome, Hope it helps. Thanks for watching!
Great video! I have a bunch of new parts to install and this will help refresh my memory when it comes time to reset everything.
I should remember all this stuff, but I got hurt pretty bad in a work accident several years ago and it has left me disabled and unable to do much of anything for a number of years and that old saying "use it or lose it" sure does apply.
Robert G sorry about your accident... but seems like you are still pushing forward and enjoying life. Nothing wrong with a little refresher. Thanks as always for your support.
Thanks and you're welcome! I like your cars and your content, so I'll be here for the long haul.
Robert G much appreciated!
I just added a Gt40 tubular intake too my 90 5.0 and it runs great driving down the road but when stopping the idle will drop low enough to kill the motor sometimes or idle jumps and before the intake swap it was perfect. What do I need to check and how to fix the idle drop issue. Will this help me possibly what your doing in the video? Thx
I have a 89 5.0, sat for 13yrs, I have replaced the entire fuel system including 22lb injectors.. new TPS, EGR, MAF, BAP, vacuum lines, smoked it and fixed all leaks and still will not run right. New O2 sensors and still getting code 41 & 91…reflashed PCM and made sure the Orange ground wire for o2 sensors is grounded good with no change…I would like to talk to you about what else I could do to fix this issue.. Thank you
Your videos are great and easy to understand. Question do you think a base reset will fix my stalling at slow speeds / stops plus running rich? I changed plugs and cleaned cap and rotor so far. Old plugs were terrible. No problems with cap/rotor and still runs rough but fine under load. It is a 89 5.0 GT motor 5 speed in a 50 Ford. Pretty bad ass. A cool fox motor in a shoebox. Keep up the great channel.
I do think it will help, it’s a great starting point for sure👍
@@BREW2LFOXBODY Thanks man. I put over 1K on it this past year and the stalling and misfires / running rich got worse. Forgot to mention plug wires are good and do not sense any vacuum leaks. Was thinking of changing TFI module or replacing the distributor as the pickup coil is known to fail with these symptoms. Thanks for the quick response and will start with base idle reset.
Also have you checked to make sure the air filter isn’t clogged... simple but often over looked.
@@BREW2LFOXBODY Attempted to set the timing today after I warmed up the car. Problem was my battery is in the trunk and with my jumper cable attached to my timing gun still was not able to reach engine bay to check timing. Anyway when I removed the spout plug from the distributor after car was warmed up it would barely idle at all. I could tell that this may be one of the issues as to why it may be running too rich and the plugs I pulled looked like crap as they were very black. I can only assume that till I get a gun on it. I think the timing is set way to low and whoever worked on it before me compensated by adjusting the idle to make it run fairly well. Would mention that it idles decent when spout plug is in it but I can here it surging when warmed up. I think when I do the base idle reset that should fix the problems of it running rich / backfiring a bit. Not sure it will help with the stalling. Thanks again for your quick feedback and my filter looks clean and not plugged.
thank you so much being gm forever I had no clue this is the best info with many years in my garage it makes sence now u the man
Really useful info,tips, and tricks here on this channel. Subscribed
My car was running pretty good until the ECU burned for some reason I replaced it with the same A9P so I went ahead double checked timing 14 degrees rpm 650 and I set the tps at .97 it feels the same only difference is when I take off is easier hard to stall now and then it feels like it has better throttle respond thanks u also had a question what did you use for your dash lights their brighter
old video but thank you! finally got my 90 gt running smooth, timing was off and tps a little off thought it was something worse
Always some great info. Great video. Keep'em coming.
Thanks!
When do you plug the spout connector back in?
I’m a kid but this is some great info for the foxes.keep up the work
iTz_ Mark2 thank you!
Hey BREW2L would this apply to a 94 ford Bronco with a stock 302 5.0 engine? and would I have to move my idle screw. I know for a fact that the idle screw is still set from factory it's never been moved.
thanks brother for the help. GREAT VIDEO.
Hi there, i have followed every step n still cant get it right,i have a 91 Lincoln mark vii that came with the same 5.0HO motor as the Mustang,,for some reason my car never stall with aic unplugged,no matter how much i play with the throtle screw to set the idle to the lowrest car still idles around 600 rpm with iac plug disconected,any ideas? Great video by the way
Hey man I’m hoping you can help me! First off, thank you. This really helped my cars idle as well as mine has an ecam . The issue I am having is when I turn the ac on. If I don’t idle it up some with the idle screw sometimes it will surge and die. Also, isn’t the iac supposed to increase the rpm when the ac is kicked on? My rpm’s drop when the ac is on not increased. Thought was a voltage issue. Upgraded to 130 amp sve alternator and still does it. No vacuum leaks. Thanks for any help.
Helped me out a ton today. Thanks
I had a question for you. So i messed with my tps sensor awhile back will that make my fox overheat if i didnt adjust it properly.? Because I'm trying to chase down a overheat issue, so far i did a new radiator water pump and thermostat and I have a vacuum refiller cornwell vacuum assist cooling system refiller Which also is basically A pressure tester as well because you pull a vacuum. I'm just trying to see where you think. I need to go from here because you seem to know these the best I think
cheers bruv, helped me with my AU Falcon 😁👍 its a bit different but works pretty similarly
Love the video helped out a lot my foxbody idels great of the start but when she warms up it likes to cut out at stop lights do u have any suggestions I'm thinking bumb the idel up a bit but have u ran in to this problem before. Love your car looks great
Glad the video helped some. You’re probably right the idle needs to be brought back up. Just keep a check on the tps voltage to make sure it’s still within range after your adjustments. 👍
Learn something new eveyday... gotta love it!
Thanks for watching! 👍
Ive been doing mine by some instructions online that didn't require unplugging the clip from the distributor. I'm gonna try your technique tomorrow. My 88 gt randomly idles super low when I come to a stop. But when I accelerate, it doesn't hesitate or anything, it just takes off without any issues. Unfortunately my tachometer doesnt work so I can't see physically what the rpms are at so I'm gonna try it by ear. Hopefully I can get it to run better tomorrow. Thanks for the video!
Give it a try. I'm no expert by any means but it always works for me. Hope it helps and good luck!
Could you do a video of all vacuum lines, ive been restoring my 91GT for 20 years and don’t know if my vacuum lines are good. Thanks
where are you putting the positive negative for the volt meter?
Great video, however this seems not to fix my issue on my 86 I just bought.. it runs perfect until the engine hits about 130 degreee then starts surging badly. Cleaned the iac, theres no vacuum leaks did a smoke test,, cant figure it out for anything..any idea? Thanks
Where did you plug the pins to get the reading from tps
Question so I can start my car with out that plug in it. I get my tps to about .96. Then I plug that thing back in and let it run. When I go to check the final tps it’s 1.111 ish. Do I adjust the tps or ideal? To bring it back down?
BREW2L, great video.....I recently swapped heads to Aluminum and added pro form 1.6 rr but the other mods below were pre-existing without this issue.When driving the car the last couple trips around the block I have noticed the rpm drops down to 500 or lower when slowing to a stop and the tranny is in neutral. If I down shift to a stop it seems to be fine. The car even shut off once but started back up easily. The car idles great after base idle reset which I perform basically just like you do here except about 8-900 RPM final setting. The car idles with/without the IAC plugged in. RFP surges a little upon start (maybe for 15 seconds or so) then levels out.Car does not have any smog or egr to speak of. Only vacuum lines are intake to FPR, intake to PCV and intake to vac tree. I don't see that any are leaking.Thank you for your input.Mods:1990 GT, gt40x heads, 1.6rr, recently added, TFS1 cam, pro flo 75mm MAF, CAI, BBK 75m TB and 19lb injectors, 1-5/8 shorty's, x pipes, bullets with dumps.
90Fox thanks for your input on the base idle reset. As you already know these things are temperamental. I have found that the 2 minute load run during the reset is about the most important part of the process. I have in the past turned the steering wheel to full lock along with all other accessories on. That way no NEW unexpected load shows up and freaks the car out. I know your issue isn't really a load problem but it might not hurt to try that along with a lower idle without the IAC plugged in. Everytime I bump the idle up to the point it runs smooth without the IAC plugged in the car seems to run worse afterwards. From my understanding the IAC needs to be the only thing correcting the idle. Thanks for watching and sharing your input.
I will try that. thank you for the input and for sharing your knowledge in this forum
Anytime! Thank you
My car idles fine with or without iac plugged in also. It keeps throwing code 54 act. I changed the sensor and it still shows it. What ohm or volt should it show when testing? Thanks
I have the same timing gun, I see you have the knob at 14° Advance. What does the crankshaft read? 14° after 0° or 24° after 10°? Thanks!👍
Hey is the process the same for a 94 sn95 5.0? Im having some issues at idle and want to go through all this, but idk how much has changed between the foxbody and the sn95..appreciate your feedback
Luv ya info but ya didn't show us how u connected the multimeter to the TPS would av been handy
This really helped me out, thank you 👍
question for you: Car is having a hard time starting. It turns over and will sometimes crank but not all the time. I have done the trick of priming the fuel pump, turn almost to crank three or four times then crank, it does not seem to help. Car runs great when it cranks. What do you and your community think: Fuel Pump, Fuel Filter, some kind of electrical issue...???
Forgot to mention, the car is coming together great. One thing I haven't heard, any plans for gear swap?
Chris aka Enlightened Eyes of the Lions Pride thanks brother, it's getting there. At some point I'll toss in some 3.55s
Thanks man this video helps out a lot, I’m at this point trying to set my idle and adjust tps since I swapped tps sensors. I got a new build and my car wouldn’t start. Due to a bad tps.
775automotive hope you get it figured out. Thanks and good luck!
Thanks for the vid , just cured my 5.0 swapped lx
Man your great i love your videos i have learned so much from you thanks man.
Thanks because I was setting mine wrong it's a different car now.💪💪💪💪💪😀😀😀
Awesome! Thanks for watching!
Thank you for this informative video. I have to do this to my car. I was also wandering, have you converted to the 130 amp alternator?
I haven't. But it does seem really strong for stock. It could have been rebuilt and upgraded along the way though.
When do you plug the timing pill back in? After everything else is done?
I have an 86 GT Foxbody with 5.0 HO engine.
Lately when I start the car (hot or cold), the engine idles at about 3000 for about 3-5 seconds and then calms down.
What could be causing this?
I have checked everything, so I’m getting ready to replace my ACT, coolant temp sensor, EGR valve and both O2 sensors.
BTW, the car has 396,000 miles on it.
Excellent video, thank you .
how far do u wanna set the idle screw do you want it closer to the stopper or back it off alot this is my first mustang so I'm learning
What bulbs do you have for your dash? I like them
Just some cheap ones from Amazon. Search my channel I have a video with links to them. But I honestly can’t remover the title to the video right off hand
just got doing this to my beater, cleaned it up a bit but still need to tweak it.. unknown cam set up with bbk junk t-body and a stripped allen set screw way out of adjustment tps over 1.4. lucky I had a accufab in the garage.
Glad you got it running a little better! Maybe you can get the rest of the bugs worked out.
that would take too long.... no idea who built this, and its staying a beater so only getting used parts thrown a it. has an eagle 347 kit and all the bolt on crap, decent upr suspension, cobra 5 lug swap, all the bells and whistles except they used e7 heads on it and the body is ruff. has some decent parts on it but damn its like they threw darts at the summit catalog total mismatch.. will be a good donor car if I can find another decent coupe.
Can I just pierce the cables from the tps? No luck sticking them at the connection I get no reading, (key on and running) . Would there be a problem if I pierced them and leave a little hole on the cable?
you should of showed how to install the volt meter and what setting to put it on. mine wont read .98 no matter what wire i put it in ect best i can get is .30s-.45 ish it wont read any higher no matter what i do, it runs fine so i just said screw it and left it be
Can a timing chain that is stretched or wore cause idle problems?
Yes. Also a bad balancer As I found out.
What wires are you back probing to get the tps voltage?
Hoping you can help, what do you recommend to do when I disconnect the Idle Air Controller the car stalls? I've got a good ide and correct TPS but am trying to diagnose a rich fuel mixture...
I've adjusted the screw to close and opened 4 revolutions (one turn at a time). Car still stalling. Return to original screw setting, plug back in and starts and idles fine with TPS 0.97
It this supposed to be done with the car warmed up or cold?
Hey, I think I have a stock 93 gt with a warm air intake, every time I start the car cold it fires right up, rev's up a little and dies. Re-start it and it's fine. Any ideas? My car sits a lot.... I leave the battery unhooked so maybe I need to do this procedure every time?
Can you make a video for a 95 5.0 base idle reset
Brew I have a 1990 Mustang GT and I’m having all kinds of problems start the car and it runs fine for a while then shut it down and try to restart but it won’t restart unless I depress the gas pedal to the floor. Then it runs for a while then starts to surge and will shut down. Please help
Man I just installed a BBK 70 mm on my 92 and I’m having all kinds of issues. I’ve tried everything here, but it’s popping like crazy, idles rough, and revs by itself. Any ideas?
You have to wait till the car is warm before attempting this right?
Yes
@@BREW2LFOXBODY just going back through the library of videos you have. Having some idle issues with my b cam. But ill get it. Also Mr. Fusiom I made works excellent.
NTH Welding I was wondering what was up seeing you on this old video. Hope you get it worked out brother.
You leave the chip out the whole time until completed?
I tried to check voltage, and all 3 wires show 5.02 volts with engine off,key on. Why is it so high? Has new sparkplugs right now. Original wires,and unsure about timing .
I'm hoping you can help.. In the process of doing the base isle reset, I can't get my tps above .68 volts. I slotted the screw holes as far as I could and still won't go over .68. Any ideas what I can do?? Thanks in advance
Your idle screw is probably set too low. Try raising it some. But if it runs good at .68 then just leave it.
@@BREW2LFOXBODY That's kinda what I was thinking.. Thanks so much for all your videos and info!!
I've had all this set up how you did yours once cars gets to Temps after 25 min of driving it likes to jump to 1800 rpm and hot start only starts to the floor and has a weak idle down to 1800 any ideas?
When do you plug the distributors timing plug back in? Id imagine when you reset the battery before the idle process but i just want to make sure
Plug it back in after you make your timing adjustment. It just kills the timing advance/retard so you get a true base time.
I could really use some help with this, i tried this and my fox shut off immediately after unplugging
my 87 5.0 revs on its own , this happens randomly. I was told its the idle air control. should I replace this or is it the tps sensor. hope you can help
Did you leave the plug next to the ignition control module disconnected the whole time?
UFOGHOSTHUNTER I only unplugged it to set the timing. Sorry I didn’t include that in the video
Perfect, I'm in my Fox's engine bay right now.
Good luck brother. Feel free to ask any other questions you might have. I’ll try my best to answer them👍
BREW2L hey my 5.0 H.O. idle to high n won’t idle down
Hey buddy can you tell me the cheapest we to do a 5 lug and dis break conversion on a 1988 convertible I just bought one did a couple on builts on old caddies but never a muscle car any info will be greatly appreciated thanks
How do I find the adjustable tps adapter plate? I tried drilling but made a mess of the tps. 😢
going to do this today, question about my 91 mustang 5.0 AOD i was driving it on the highway after a new stall converter, plugs rotor and cap fuel filter. i gave it alittle bit while driving and it felt fine all the way up to about 85-90 mph and didnt go any further. almost as if it had some sort of governer. any ideas? still havent done the base idle reset yet
