When I press the clutch and let off the throttle to shift gears, the rpm's will hang for a second or two before dropping off. If the weather is cold and the car is still on fast-idle after a cold start, the rpms will actually increase slightly before dropping off between gear changes. Another symptom is my fast idle is way too high on cold starts. Rpms will go to 1800-1900 for a few seconds before dropping down to a reasonable rpm. The higher the rpm I shift at, the longer the delay is in the rpms dropping off. Intrestingly, this only happens during a 1-2 or 2-3 shift. Does not occur on the 3-4 shift even under heavy throttle.that does seem high for a rolling idle. i'll have to check what the stock setting is at when i get home.
as for the throttle hanging, can you describe more? there is a feul cut off when the clutch is depressed.
