Takes a little bit for rpm to come down

[Woody103]

I just got my 94 gt running after sitting for two years it seems like the rpm’s do not drop right down after I let off the throttle . Like when shifting the rpm’s stay up when I’m shifting kind of hard to explain but hope you know what I’m talking about .

Oh yes....we all know EXACTLY what you are talking about! Hanging rpm and hanging idle is synonymous to sn95's

Anyhow, get your car running and go over all the vacuum hose, intake pipe, and intake gaskets. You are looking for any air being sucked in from anywhere other than through the mass air meter.
