IAC= Idle Air Control valve, btw. I would recommend using throttle body cleaner instead of carb cleaner. Carb cleaner is an ether based product. If the throttle body has any coating on it, the ether will eat it away. That rear hose has coolant running thru it, remove it before removing the throttle body. The last thing you wanna do is introduce highly flammable shit into the cooling system. Also, be sure to clean that throttle body gasket well to make sure you don't have any vacuum leaks. 1k rpm is still a bit high, if an auto you should be running at about 900 rpm without ac or defrost on, may wanna replace the cold start injector. You'll be running rich the entire time, bad mpgs plus advanced spark, it'll ruin your cat and your timing will be off because the engine will always think it's cold, flooding the system. Just my opinion though...
This is all great advice. However, there is no cold start injector on this engine. Sounds to me like the IAC is trash, especially since the rpm is still at 1000 after cleaning. Normal no- load idle rpm should be around 650. NEVER re-use a gasket on or in any component, always replace with a new one!
I cleaned mine and it's a temporary fix. The rpms eventually drop on starup but not like a normal car. It should take 30 seconds to a minute. Eventually the problem returned and the only thing now to do is replace it.
I'm having same problem ,but when engine warm up 3-5min then it goes down 89 straight 4cylinder truck thanks on video I actually learned alot have a good day 💯💥🤑🤘🤘🍻
You might have to do a relearn procedure to get it to where it's supposed to be. Something isn't right when it's idling at 1K, should be around 700 + or - 50 roughly. Search for Toyota 4Runner Forum IAC Reset Procedure. I don't remember exactly but you cycle the key on and off and hold the odometer reset until it beeps, wait 5 seconds, hold it until it beeps again. Oh no, wait, that's the gas gauge reset.
You didn't cleaned it properly, i can see its still dirty and have have carbon deposit on it...try to remove the carbon deposit with the cotton bud with carb cleaner and see the results....it will settled down to below 1000/rpm
@@feesh00 Not sure where you are but in many markets this truck doesn't support OBD2 nor have an OBD2 port. To read codes you just short E1 and TE1 in the DIAG connector on the manifold and count flashes of the CEL.
I don't know about you but I have the same motor 5VZ-FE on my 2000 Toyota Tacoma i don't know about you but i have the same motor on my 2000 toyota tacoma my idols at about 500 rpms and I have over 412,000 Mi on the motor

I liked the music. Thanks for the video Serge.

I have to agree with the others, video gets a 7 & music gets me turning the channel.
Very helpful 👍
Thanks 🤙

I cleaned out my IAC and now I have a high idle.
How did you clean it? Did you use a solvent? Rag? Spit?
I used carb cleaner because that's what I had but anything tht could get all the build cleaned out works too
I’d use carb cleaner
Good video i like the music
off topic but what exhaust do you have? sounds real good
how about my toyota vios 2014 same problem idle high
Hate it when people put goofy loud music on their video's
Nice I'll keep doing tht
Great fix mate, have a 5VZ myself in a 2000 Prado. Mine idles between 750 and 1000 depending on if it's in drive or not and AC clutch engagement.
Glad this video was helpful! Same here idles at 1k and when in gear drops to about 650 to 700
Hello Stuart Gunn
I have the same prado model and i can't find the OBDII port!
Can you help please ?

Awesome thanks
What kind of muffler do you have?
idle should be 700 +/- 50
01 tundra 3.4 fixed
Awesome video horrible music
Who asked?
Serge Mednikov true hurts
agree
No music is better don't get offended you want feedback I would think
@@theexterminator1 no j don’t. Your video is awesome. Probably your throttle body sensor. The one with the spring
I don't know about you but I have the same motor 5VZ-FE on my 2000 Toyota Tacoma i don't know about you but i have the same motor on my 2000 toyota tacoma my idols at about 500 rpms and I have over 412,000 Mi on the motor
01-02 4 runners are different
Didn't work
Try adjusting throttle cables, usually lowers when warmed up
why your voice very low
That music sucks.
