03 Mustang Gt Stopping Poroblem
My 03 Gt has recently decided to lose its mind. I replaced the IAC to fix an idling problem but not it wants to hang at 1500 rpm when i’m stopping and will not let off until it’s completely stopped (sometimes easier said than done) and when its stopped, it jumps down to 400 and almost dies out. I’ve looked through a few posts and haven’t seen much like it in an automatic car. I’ve checked for vacuum leaks and nothing came up. A few guys at work thought my throttle cable was hung until i let them drive. Seriously need help on this one. Thanks in advance

Clean your original, and reinstall. See if it isn't better. In my experience the aftermarket nonford IACs are garbage.

+++^ KAST1376 has a great point, just because its new doesn't meant it works.
There are a couple post on here where someone had to return it three times before getting one that worked I think it was Tadpole or something like that
