Idle on the 90Q20V is supposed to be 950. Mine is right on there. My
100Q idles at 820.
Other than that, my 20V is having some of the same problems. The car
failed the vaccuum test (opened cap and dipstick, car didn't even hiccup).
No vaccuum leak found, though.
I don't know what to try next. Have you checked plugs, cap, and rotor?
