I just got done swapping a 96 Tacoma from a 2RZ to a 3RZ, I got all done and the idle was odd, this video helped me fix the issue, it was a throttle body/IAC issue. Now I have a great running 96 xcab 3RZ 2wd 5spd taco, thanks guys!
excellent, thanks for watching and commenting, we appreciate it.
سلام عليكم ورحمه الله وبركاته معي تاكوما موديل 2000 تكون تدعس علا البنزين. وتكون نفس المكضوم 16:25
You give a great explanation of how this system works.
thank you and thanks for watching!!
I sprayed about a can of carb cleaner into the throttle body without removing it - sprayed the MAF clean and my truck is at least running now. I did screw around with the front throttle adjustment screw (no idea what I'm doing) - but, I set it so it just rests nest to the plunger. At least my truck runs now - I am pleased. I have bookmarked this video in case I have to take the deep dive and removed the whole thing - you listed links for the parts I would need. BIG HELP! Thank you for this video. I'm a 67 yr old nerd and this was my very 1st DIY truck repair! I felt like I knew what I was doing. I am wondering why the three vacuum hoses on top are missing on my truck and just have blocked-off "caps"?
These engines are great. You did a super great job. Good for you and thanks for the video. 🍺😃👍
Great detailed video. Helped me out a lot. Thanks
This is a very helpful video, thanks alot!!
Great video, sounds like you might be a certified mechanic
Wow My PROBLEMS SOLVED ........Thank you soooooooooooo much
Very helpful, thank you!
Awesome job thank you very much I was going crazy lol 😆
My Tacoma would not idle. Took the throttle body off cleaned with some carb cleaner now it works perfect
DUDE!! thanks for the edumocation! 00 toy is sick and AutoZone keeps taking my GRINGO DANAROS!!! lol 5 trips and its sunday night!! no ride yet
Do you remember the parts number for the idle air control motor? I have been having an issue with my 04 Tacoma and there is no check engine light so i don't think it would be my TPS
After literally years of getting a surging of the idle on my Taco, I think this is the video that I've been waiting for. This just lit up my brain as I saw you tinker with all of this and I think this is the source of my Taco's wild fluctuations of idle at a stop sign. Sometimes the vehicles surges so much that I worry that I'm going to hit the person in front of me. This helps SO MUCH! Thanks buddy!
awesome!!! thanks for watching and commenting, we appreciate it.

I have the same issue, how did u solve it? Adjusting the idle?
@@olivermarquez6793same problem here
Great video, learned alot in just a few minutes. Esp adjusting the kick up.
Truck has been running perfect, 25 miles to the gallon, purring like a kitten, with 250,000 on it.
I have my 04 tacoma in dealership for this issue. Hope the replacement of tba works so I can start to enjoy driving it again. I’ll find out by end of week.
Yes, Keith is right, if you clean the IAC and the TB, you shold not have to touch the factory settings. You
said earlyer that someone had adjusted them, but if the paint was still there it was not adjusted.
I just changed the IAC and the rpm is always at 1500 to 1700, before changing it they were at 700, with this video I already know how to lower the rpm, thanks
Congratulations?
it worked out?
@@danilomewes8731 yes
Thanks Mike....
Hi 👋, really good video 📹. Nice close up camera work and great walk through on this procedure.
I have a 98 Toyota 4Runner with the 2.7 L (just had a top end rebuild) and it's having a different twist in idle. Mine starts cold correctly at 1200 rpms but when it warms up the idle drops to 650 to 700 ish and runs rough like it wants another 150 rpms to smooth out.
If I manually raise the idle at the TB up a bit (approximately 150 rpms) the engine smoothes out fine. Both idle screws you pointed out in this video are still at their factory settings (as evidenced by the yellow paint from the factory).
Should I just adjust the idle up a bit or is this evidence of some components not working properly?
What did you end up doing?
Thank you
Just a hot tip, upper cable on cam is a Cruise control sencer cable.If Cruise control didn't work take up the slack in cable Wala it will work.
Great help, thanks
thank you for watching!
عندي تاكوم تدعس علا ادعسه لاتستجيب
Is there a video of the fuel filter change?
Buen video 👍
Was this vehicle under water at some point ? Do any of these guys ever lubricate ANYTHING in the engine compartment ?
Great Video
Thanks!!
Is that pressure regulator vaccum hose hooked up to air cleaner?? How Gould that work don't think there is enough vaccum to keep it open at idle ..does it works different??
Hello! I have a question....when the engine is idle in normal temperature the screw should be touching the throttle opener pin? Mine has a gap
How did you diagnosis that the idle air control valve was bad?
hello. what is the name of that part that moves the accelerator when the engine is cold. It would help me a lot to know the name of that piece. Thanks a lot
Tell more about those angled needle nose pliers please!!! Need those babies!
My tacoma 2.7l auto at a stop sign after warming up at a redlight will have a rough idle and yes ive done all the cleaning and changed the spark plugs.
where do you get those vacuum diaphragm boots
I never did see you reconnect the IAC.
I am having a sticky flap problem in the throttle body of my 2003 toyota tacoma where the flap is sticking causing an inability for the engine to get air and also causing the truck to lose power
I have a 01 Toyota Tacoma 5 speed, and my alternator seized up and shredded my belt, 8 months later I replaced the alternator and belts, and she turned over good. Changed the oil and filter. Drove the truck for about 10 miles and now my idle is messing up. Whenever I come to a stop, my RPMs drop out and I stall. I have to keep my foot on the throttle in neutral to keep my RPMs up so I don't stall. Should I look into a possible IAC problem?
I’m having the exact same problem after changing alternator. What did you ever figure out? Was it IAC?
Im so confused. I assumed you would replace the diaphragm. Instead you made an adjustment on the nut that is supposed to be factory set.
My 2.4 tacoma has a high idle and when I took off the vacuum hose its rpm shot up 2-3 grand. Any tip of diagnosing and also it has 311,000 but it idles what it sounds like 800-1000
Did you ever figure anything out
I have a 02 Tacoma and Everytime I put gas in the tank the RPM go up and down for a couple minutes, any help why is that happening?
Should I use some threadlocker (Locktite) on the bolts for IAC?
need help finding the throttle opener/dashpot part number for my 1999 tacoma 2.7
please help mine is blown i can't find anything
I havw an 02 but my idle is 1k rmp on park and or neutral
Good 👍
It happened to me and it was the broken diaphragm, It's weird how while he was connecting everything again it's clearly shown how the diaphragm was not working. Unfortunately, that one is not sold by separate. My jeep had a 3RZ-FE so I took one from a tacoma on a junkyard and after I changed it, problem solved.
Today we have a Ford Tacoma...
🤣🤣🤣I had to restart it to catch that
He said “2004 Tacoma”
Can someone please explain what keeps RPMs revved between shifts on a manual transmission.
It's called rev hang. Toyota does this on purpose because of emissions.
hello i think you do not know what are u talking about that valve is dashpot for smooth deceleration to idle so engine do not chock and works with manifold vacuum.
...@10:25..the replacement idle control rotor has a larger slot....
This video was extremely helpful. It gave me the courage to remove and clean the throttle body and IAC valve. Unfortunately my truck isn't idling correctly. The idle is high. I guess I will replace the IAC. What brand do you recommend? The pricing ranges from $20 to $400. I found a Standard brand (ac526) on rockauto and ebay for a midrange price. Please comment
I bought an IAC for around $70 a while ago from Walmart online. I noticed, however, that with a lot of WD40 and a very narrow flat-head screwdriver, I was able to unstick the valve in the old one, which should be closed. Mine was stuck open which caused a high idle. It looked serviceable after I cleaned as much of the carbon out of it as I could. The valve moved freely as it is spring-loaded. I put the new one on all the same and will hold on to the old one as a spare.
@@sissonsk thanks for info. I haven't driven the truck since I cleaned the throttle body and IAC. On few occasions I let the truck run for 10 minutes. The idle when the engine is cold is low but increases as the truck warms to operating temp. Idle speed is reverse of what it should be.
How about my 03 tacoma.idle run 2000 rpm.please.I did replaced idle sensor.thankyou
How do you fix this
Mine does this when its cold sometimes
What if idle is to high 1700 rpm?
It will eat up your gasoline very fast..750-900 is fine
wish you wouldve showed the rear bolt to adjust bro
That rear bolt for the low-idle adjust is a real pain to get to when the throttle body is on the car. With a metric allen wrench and metric open-end and box wrenches, about the best I can manage is 1/8 - 1/4 of a turn at a time, so it takes a while to turn that thing in or out 3-4 turns if you are adjusting it from scratch. If it's just a little out, it's not too bad.
Que se pudiera ver y escuchar en español
at about 18:30 we cannot see what he is adjusting and you need to understand just what he is doing when you cannot see it
Not sure exactly what you are referencing. The first thing he does is rotate the throttle to rev the engine, next he removes and attaches the vacuum tube to cause the plunger to move back and forth, and finally, he adjusts the nut and bolt to change the resting position of the plunger.
Yo vusco una tra a mission para toyota tacoma año 204 automatico motor 3.4L
Am i the only one who got botheres by all the rusted clamps on the car😂😂
the gap is even bigger that dont make sence??????
It's not just the gap. What matters is that the plunger comes out enough to raise the RPM by 500 rpm when the vacuum hose is removed. The whole video makes me wonder if the IAC was really bad, or if the low and high idle screws were just way out of adjustment.
IAC will never throw a cel
My 99 Tacoma is idling way to high...and don't know what to do?
Rob Robinson take the throttle body off and clean it thoroughly. Then take the IAC, very similar to this video(if you have 3.4) and clean it out with throttle body spray, toothbrush it, swab it, and airhose it dry, ports also. Should be good to go. But this is 2 months later...
Don’t clean the edge of throttle plate, or the throttle body, with spray cleaner while the throttle body is installed. The IAC motor is located below the throttle plate. Gunk removed by by the spray cleaner will flow into the IAC motor and ruin it.
Same truck and mine just stopped doing anything when i push the gas.. throttle cabke still moves.. just a pos..
