Strange Idle Problem 1994 Mustang GT
I just installed a 70mm TB onto my Stang. Before installing it I cleaned the heck out of the IAC, but ever since it's all been installed I have a strange idle issue...
When I first start it it wants to idle a tiny bit high (maybe around 1K RPM or a tiny bit more) but when I start moving the idle will only go down to around 2300ish RPM... until I come to a complete stop. Once I come to a complete stop the idle will come back down to around 1K RPM. But if it's moving at all the it only idles at 2300ish.
Does this sound like an IAC, TPS, or vacuum leak?
