Asking About: Mustang Idle Air Control (IAC) Adjuster (86-93) EFI V8


hanging idle?

my idle was really rough when I picked up my fox with a e303 cam. I heard about this through a friend and decided to try it. idle is fine now, and it really helped on cold starts... but now it seems to hang at around 2k rpms for about 10 seconds after I left off the accelerator and put the car in neutral. (manual trans) any suggestions? maybe my iac is bad?

It sounds like your iac is possibly just sticking. I would remove it and clean it out with some carb cleaner and see what that yields.
