ok guys i'm about to go nuts. This problem has been happening for like a month now. I have a 70mm inlinefour TB. I reset the ECU and the car idles at like 1000 but then i drive the car and it warms up and it then idles at like 2k. I have tried everything anyone can possibly think of. I got a brand new IACV, checked the voltage on the TPS, checked the MAP, adjusted the idle screw, everything u can think of....and it still does it. Any help would be appreciated more then u could imagine. Thanks guys

 

you try lowering your throttle stop screw ?

 

yeah, i tried adjusting both screws

 

have you checked of you TB gasket is leaking?

 

this belongs in the tech forum

 

have u checked if ure throttle cable is too tight that might prevent it from closing all the way.
