Hey I have a question about my 3.8l 01 mustang. Whenever I push in the clutch (or move to neutral, either way) the engine hovers at that same rpm for a couple seconds before it SLOWLY goes down to idle. Is this normal? Is there some sort of throttle control that causes it to close very slowly like a dashpot or maybe a sensor problem could anyone help me out? It is a longer slower return to idle than any car i've ever driven. Shifting into 5th is becoming difficult unless I double clutch it
Engine "floats" too long?...

Make sure your idle air control (IAC) valve is clean, or is not defective, and if so consider using a "IAC restrictor plate". I don't know exactly how to configure one for the 3.8L engine, but I use one on my 5-speed and the difference between having it installed and not having it in place is night and day as far as eliminating the hanging idle issue.

Yeah it's normal to have the rpms stay up a few seconds. They do that to make it smoother between shifts and smoother when down shifting.
