I have a 2000 Mustang v6 manual trans with just over 40k miles. It seems when I put it into first it will take off without stalling just by releasing the clutch and not touching the gas. At stoplights when switching into neutral it seems as if the throttle will hang longer then normal but eventually drop back down. I cleaned the IAC and replaced the TPS but nothing has helped. I am stumped? I would defintley appreciate some insight and opinions...Thanks
