Ok, I have a 92 9k turbo tcs auto that has a drivability problem. 1st, when idling in either N or P the car has a stumble/miss. Sometimes shortly after starting the car there is a hesitation, pressing the gas pedal down does nothing, it only maintains the speed you are already going. So if you are accelerating from a stop, it will slowly accelerate same as usual except the gas pedal requires far more motion to make the car go. ie. for every 1/4 inch you would normally press the pedal down, you now need to press it down 1 inch to achieve the same results. The car in general while doing this seems very underpowered. Once the car has warmed up, the problem goes away, except for the stumble/miss in the idle. The DI cassette has 70k miles on it, the plugs which are the right NGK ones are about 25k old and gaped properly. I sprayed carb cleaner on the throttle body and wiped it up with a rag, but that didn't do anything. I think it happens more often when it is wet out. Maybe not, could just be the fact that it has been wet a lot lately.

Any and all advice and comments are welcome :)

Thanks,

Jeffla
