Hey guys last night we were doing a little road tuning on my hta3794r evo that has aem and when i pulled into a gas station shut the car off then turned it back on the car would not idle at all! I think its the iac valve as it would not reapond to any idle changes we threw at it but if anyone has different imput please chyme in!!!

 

I dont have an aem ecu but i use a tactrix cable + evoscan and i can disable the iac sensor... find out if there is a way with aem. If you disable it, you set your idle with the BISS screw ontop of the throttle body, then you reenable the iac and it should be better. Also, being low on coolant could make it idle wierd.. check that out.

 

hmm thanks bud ill check into that

 

Coolant is perfect do thats not it
