Overspeed

[MisterCMK]

Hey guys, I've got a question for ya. I have a 94 gt with a manual tranny, and i'm having a problem with it revving up a little between shifts. I take my foot off the gas completly, and she still revs up when you put the clutch in. I've never had a car that does this. I am not sure if it is normal or not. thanks for the help

that is called hanging idle. There could be a number of things wrong. A lot of the "common" problems is the IAC. Clean your MAF, TPS, and a couple other sensors.

Its VERY common on our mustangs.

DO these steps and it should solve your problem:

More then likely its the TPS (Throttle Position Sensor)
