rough idle

[goliath]

when stopped and fully warmed up my idle speed drops to 500RPM. A slight rough idle can be felt. too few rpms if you ask me. i put the tranny into neutral and the rpms go to 700. back into drive and they stay at 700.

happens every time. anyone else experience this?

I think I have the same thing you have. It happens after it has started to warm up. The car feels like it has a hard miss which shakes the car a bit. Mine goes away but only after the car has fully warmed up.
I had it looked at the dealer but htey could not find anything... I plan on taking it back

Do you guys have a tuner installed (SuperChip, etc.)?

I have exactly the same problem... fully warmed up... seems to happen most when a/c is on its lowest fan setting... I've had it stall out 3 times during a rough idle incident, but like previously mentioned, if the dealer can't duplicate the problem, and the car doesn't leave a code trail, not much you can do but stomp your feet and throw a fit.
