Has anyone experienced this problem with there Corvette?
I own a 1991 Corvette with a L98 engine. Since this spring I have replaced the following:
Battery, in-line fuel filter, spark plugs, spark plug wires, distributor cap and rotor, idle air control valve, throttle position sensor, adjusted and set timing to factory specfications, Front Y-pipe w/pre- cats, Catalytic converter, rear y-pipe, and mufflers.
The car runs very well on start up; however after the engine warms up there is an idle issue. The RPM's can fluctuate 2-3 hundred RPM's. After 1200 RPM the engine runs very smooth (hot or cold) yet if I am traveling on a back road and the engine is operating at less than 1000 RPM again the RPM will fluctuate. Also on a number of occasions after the car is warm it will either not start (until it cools down) or it will start and run for a short time and stall. Yesterday, the car started, I backed out of a parking spot and the car stalled. Last week the car started, I drove out of a parking lot to a stop light and the ar stalled. I will need to let the car cool down and then it runs fine again until it warms up again. When hot the car idles at around 600 RPM (but fluctuates between 600-900 RPM).
Thanks for your Help
