I have a 2002 3.8L 5 spd and the engine RPM will stay hi between shifts. I have cleaned the intake TB and replaced the IAC. I removed the IAC control wire and drove the car and it did not do this. Yes it did want to stall. The idle is ok and cold start is good. I would like to test the TPS at idle is the idle voltage still .5 to 1V? for this year? Thanks for the help
Thanks guys for the help. The MAF is cleaned, the stop idle is set at 500RPM w/IAC off. And she still will stay high like 1st to second gear 1500 to 2500RPM and very slowly come back down. P.S we checked for vac leaks too.
