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 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
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.
@@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
