Ok car has Mods listed in sig and i am haveing a problem with idle when i start the car up it try's to die and then the IAC catches it. even when its warmed up if im cruiseing at any speed and at WOT its fine actually very smooth but when I take it out of gear and hit the brakes it wants to stall and sometimes it does stall. the only codes I had were a random cylinder misfire which my tuner says thats because of the cam ( im still running OBDII ) and Bank 1 sensor 1 which is the driverside front was bad so I replaced it and it still has this problem, I also checked for vacuum leak and found nothing I even adjusted the idle screw all the way and nothing so PLEASE help for the love of God

Thanks

Im not positive but i have seen some things about the aftermarket throttlebodies do not idle very well because of the size of the idle air passages. and two your iac can fail and not through a code all the computer knows is that it is telling the iac to do something but it might not do it. and it also could just be dirty i would replace the iac with a new one and see.

The Iac Is Only A Couple Of Months Old And I Checked It Anyways And Its Clean I Cant Find Any Vacuum Leaks I Dont Know Maybe Its The Tune But The Guy That Did It Is Very Reputible And Did My Last Car And It Was Fine And It Had Twive The Mods
