Good Job............My Friend
Thank you🙂
Awesome video. I will do this job today I think, since you made it look a lot easier than I thought it was. Can you make a video getting rid of that ticking sound? pretty sure it's a valve adjustment, and I have the same sound in my 4runner. Cheers man, thanks for your video.
Thank you🙂 hopefully everything goes smoothly..well it was a customers truck but if he does need something serviced ill be sure to ask if he wants that done🙂
How about cleaning the black crud off that butterfly flap before re-assembly..?
2000 Corolla uses a very similar IAC valve. Impossible to open it up (removal from the throttle body is easy... but access to the rotating barrel end inside is insane), but an entire replacement valve may be the safest method to resolve a rough idle and fix the problem... if that is where the problem lies.
Great tip, thank you🙂
Thanks. Now I think I know what to look for. You think I could just plug coolant lines? I just put in a new radiator, I don’t wanna drain it again.
Well that coolant like on bottom will come out pretty fast so if u can get it off and plug it fast, u should be able to get away without draining it
Thanks
Anytime🙂
Thank you very much for the great video! It looks like you for got to scrape off the old gasket on the engine??
I did, i cropped it out to shorten video since its same steps as i showed on throttle body...whats left is just a rust color it gave the metal from the coolant that would hit that area
@@backyardchevy328 Ah! I figured you might have, LOL! May YHVH bless you and protect you.
@@zachreyhelmberger894 thank you🙂
0:30 do i run this by pass with the hose off or on ?
Does this only happen when hot and not for the first 10 minutes or so thanks
Was your car a manual trans ot automatic? Thanks
Air leak on the intake tube between the MAF and the intake manifold will also cause a surging idle on the V6 3VZE
Yes definitely..any air leak after maf is airflow thats unaccounted for...so the computers adjustment with fuel will not match..causing too much air for the fuel mixture
Could this IAC valve also cause idle to return to a very low idle only a day after opening the idle screw ?
Thats what happened after i replaced the idle air control valve and the truck got to operating temp, the thermostat opens allowing coolant to circulate and the idle air control valve opens then the idle will drop.
So I ran into this problem a day into owning my 1994 pickup it drove fine but once I got home and put it on park the idle kept going up and down. I had a similar problem with my 1998 Honda Civic so I knew imminently knew what it was but on my Honda the car kicked and jerked while I drove it was scarier than the pick up but when I went to buy the iac valve it only came for manual transmission but my pops a owner of a 1991 pickup told me they’re the same part
Were u able to get it fixed?
@@backyardchevy328 I did actually it wasn’t even the iac valve the truck was just at the wrong rpm simple as adjusting the idle screw lol
@@matexf4c glad to hear it just needed a screw adjustment 🙂👍
Just what the Dr. ordered, thanks for the tutorial. Question if your still around, can the IAC be cleaned on this model Toyota? Thanks again!
Yes, it can be cleaned but depends on what the problem is..if its just all gunked up and dirty causing it to malfunction then cleaning it would solve the problem..on the one in the video the actual motor was bad..the resistance was high on the motor.
@@backyardchevy328 Thank you. How do you tell if that's the problem? If it's a bunch of work forget it, I have very little knowledge when it comes to electrical.
@@donr6234 when i removed it..i just tested the motor resistance using a multimeter..i wish i had included that in the video..but i felt it was becoming too long
@@backyardchevy328 I don't see any electrical connections on my 1990 Toyota DLX 4x4 IAC, is there one at all? Thank you for all your help. 👍
@@donr6234 oh no it should be the same ur right..im confusing it with another toyota idle air control valve i did more recently..u could try cleaning it..but for the work involved and i gave my friemd the option of either replacing it or trying to clean it..he just decided to replace it..especially since it was lower priced on amazon
when i order this part # they said it does not fit my 1986 4runner 2.4 engine. i am confuse.
For the 1983 to 1989 the idle air control valve is a different design so that part number wont match...the one i used is for the 1989-1995
My 94 22RE pickup surges up and down only when I push on the brakes. I’m thinking it’s the TPS but I’m not sure.
That could be a leaking brake booster thats creating a vacuum leak as u press brakes.
Got a 93 Toyota PU and have the same break surge after I sprayed throttle body cleaner directly into the TB with valve open and scrubbed inside with a toothbrush. Did I mess up somewhere? Thx for the clear vid! Liked and subscribed!!
Just completed what you did except I stripped my screws holding the IAC in place. Did not know there was an impact screw driver invented. Any suggestions on how to get the screws out! Tried an "easy tool" but to no success.
What i would do is i have a cut off tool not sure if ud have something similar..or maybe a saw blade would work..i would cut a slit in middle to make it able to use a flat head screwdriver bit
will try that trick.
@@redrhino4370 good luck..hope it works🙂👍
What is that other little round peice coming off the throttle body connected to the throttle cable?
u mean the deceleration dashpot? if so its meant to keep the throttle body from closing too fast when letting go of gas pedal
@@backyardchevy328 did you add some cable/wire to the dashpot? If so, could you please tell us why? Thank you.
@@chacholiades lol i didnt..it was on there before i worked on it..i was still wondering what it was doing there..didnt seem like it was actually doing anything
I have a 95 4runner with a v6 3vz-e and I'm having idle surging problems 2k-2.5k up and down what should I check first
Did it start all of a sudden? First thing i check is the coolant level since those idle air control valves use the coolant level to adjust the idle...after that i start checking for any damaged vacuum hoses or a bad pcv valve..any check engine light?
a dirty MAFS is cheap to clean and easy to remove (be careful with the delicate screws). It's one more thing to eliminate that deals with air flow...
Does this apply to the 3VZ-E?
No the 3vze have the idle air control valve as part of the throttle body, so the throttle body setup is different
Does anyone know if the idle control valve or the 22re is the same for the 3vze 3.0 L V6?
No, theyre different...i believe the 3vze has it part of the throttle body
@@backyardchevy328 So if my IAC goes bad i will have to replace the whole throttle body?
The issue i am having is that my truck intermittently idles low and rough at start up then stalls. I can't get it to start again unless i let it sit for a while.
@@ag11b69 yea i believe so...cause i dont think they even list the idle air control valve for the 3.0l...and yea that does sound similar to the issue on that truck except the idle was a lil higher than urs probably is.
My idle control screw goes down on it's own any idea on that? Can't seem to fine any answer
Does it still have the oring? Its probably missing or damaged, that would cause the screw to be able to vibrate down
it should have locking ring to snug down once the inner adjuster is set right...
Where did you buy the IAC valve?
I ordered it off of amazon
I changed my iacv and my tps & checked my timing & my truck still idles like crap and dies at idle, has good get up & go just doesn't like stopping. I'm currently looking for a ecu to test to see if that's it. If any of you have any idea let me know thank's.
Did u adjust ur idle at operating temperature? Is it a manual or automatic?
@@backyardchevy328 it's a manual 5speed , yes I adjust my idle at operating temperature. with my tps unplugged, would not run, I tested the tps plug coming from the wiring harness and the very top hole "lack of better terminology" is about 4.8 to 5 volts & 0 on both the other's & 11.5 volt coming from the very bottom. I can't find anything about what the proper voltage is supposed to be going to the tps from the harness, 11.5 volts seems for what it is & does I'm probably over thinking it, I really appreciate the reply thank you.
@@brianp8144 have u tried connecting a vacuum gauge to see how the vacuum is..if it has trouble idling but runs good when pressing gas, it could possibly be a pretty big vacuum leak somewhere, and if thats the case the vacuum on the gauge would be very low...and if it is low, could be a hose thats torn or maybe a bad gasket somewhere
@@backyardchevy328 I'll give that a shot, Vacuum gauge are pretty cheap, I'm pretty sure that it's a bad tps, I can't get either of my 2 tp sensors to infinite ohm's when testing idl & e2 on the tps it's self no matter what I do, jumping te1 & e2 on the diagnostic port dosen't do anything either supposed to kick down to baseline timing. Thank's again man I do appreciate your help and time.
@@brianp8144 i hope your able to figure it out, if u do please let me know what it ended up being🙂
Why did you not clean the throttle body plate while you had it off the intake?
I should have, but i thought it would make the video too long if i showed that in the video as well.
Why did you not clean the gunk and carbon on the throttle body?
Well i would have but i wanted to show that the repair came from the idle air control valve replacement
@@backyardchevy328 Ok. I did not know that. However, the idle and performance will improve with a thorough cleaning!
@@orinmangar2333 yea it definitely would
Yooooo!!! Wth I have this same issue with my Yota 90 3vze. Is it pretty much the same steps? Or different
Well on that model the idle air control valve is part of the throttle body
@@backyardchevy328 Awww snap 😧 so I would have to replace the whole thing? Or what would you suggest please. I have this same issue with it revving up and down.
@@backyardchevy328 thank you for answering my question so quick.
@@vegaf2011 maybe u could try cleaning the whole throttle body thats what i would do, and clean out the coolant passages..if theres gunk in there and ur able to get it out..it could help it work like normal
@@backyardchevy328 Thank you. I'll most likely get to cleaning tomorrow 🙌🏻 any recommendations on what I would use to clean please.
Where did you buy those parts?
I ordered the idle air control valve and the gasket on amazon..i got em for a lot better price than auto parts store
@@backyardchevy328 do you have the name , or the link , we have a 1991 toyota pickup and it is having problems
@@nathygalan9005 www.amazon.com/dp/B000C7WQTO/ref=cm_sw_r_apa_i_u0cWEbASDQKQ2
Be sure to clean the carbon out of the throttle body before reinstalling.
Yea, definitely...i should of done it myself..but i tried focusing on iac valve so people wouldnt question if it was cleaning throttle body that could of fixed it

Good instructions and easy to follow. Note that you can simply use cheap clamps on the coolant hoses to avoid having to capture all the leaking fluids. Lastly, you'll gain more respect from those who care about their engine by simply washing your engine before you do a video. Thank you.
Thank you🙂 yea they do look much nicer when cleaned but it wasnt my truck..great tip on the coolant👍
You forgot to clean the throttle body from the inside
I was going to, but for video purposes i kinda wanted to show that it was the idle air control valve that was the fix.
Muy malo para trabajar hay que limpiar el cuerpo de aceleración te falta mucho para aprender hay que ser higiénico en el trabajo acá en Guatemala si trabajas así no comes !!!
No es de ser malo para trabajar..es que mi video queria comprobar que era falla de la valvula..si le hubiera limpiado el cuerpo de aceleracion le hubieran tenido duda que era la valvula..y solo por eso no la limpie.
I don.t know about you people on car problem fix speak up sounds like you got a hang over but I've been there it is a head ace. N more.
Crap
Whys that?
