2003 GT
108k on the clock
RPMs seem to hang at initial start-up and when coming to a complete stop. They eventually drop to normal idle RPMs and there is no stumble or rough idle. I think it may be a sticking valve, because fuel consumption has not increased and power levels seem fine.
everything air related between the TB and exhaust manifold is original 2003 stock.
I've listened for vac leaks, and can't seem to hear any.
Any other suggestions before I take the IAC off for cleaning/replacement?? Is there a how-to write up somewhere??
TIA
