So i got this 2.4 22RE Toyota Pickup. The idle has been whacked since late January. I replace the Throttle positioning sensor, spark plugs and wires, rotor and rotor cap, and pcv valve. In addition, i cleaned out the vacuum hoses and still nothing. the video provides a more insight into my problem. Any help will be greatly appreciated!

thats how i fixed mine.

 

I've had this problem on all three of my 22res at some time or another. All of them were due to the coolant level being low.
Mis-aligned TPS, IACV malfunction (clog, valve not working) and incorrectly set timing and idle speed can also cause this. I know you said you replaced the TPS already, but is it set correctly?

I know its for the 4runner, but its the same stuff

 

i'm almost certain that i set the TPS correctly. I used a multimeter to set to the proper range. The coolant is normal. the only thing i can think of it the IACV. I was not able to take it out but will try again.

Thanks for those two files! I really appreciate it.

 

well i took out the throttle body once again and was finally able to detach the IACV. i sprayed carb cleaner and it would not drain it, i figured there was a clog so i started to bang it against a hammer, and sure enough, a clog about the size of pen cap came out... it was a blue shop towel.... idle is now normal and is working great...
thanks for the help!!
