1988 Chevy Celebrity - 130,000:
after about 2 mins of idling on a cold start. My car will throw a check engine light and at that very moment my car will go from running very smooth and good, to very rough erratic idling.
wile this check engine light is on and my cars speedo doesnt not work and the odometer does not roll and calculate the miles I travel.
sometimes when car is at normal operating temperature it will not keep an idle and will stall, once stalls it wont start, it is just cranking, and when this happens I am still getting all spark to all pistons.
sometimes wile driving I would have to keep my foot on the gas for it to start running and sometimes it will stall at a idle when the check engine light comes on.
also at times when driving wile the check engine light is on and my car is running bad out of no where in the blink of an eye my check engine light will go off and all at once the car will like it would normally and my speedo would shoot up to the speed I was traveling at and my odometer would start to roll again. This has been going on for weeks.
I have a brand new ignition module, coils, plugs, wires, air filter, fuel filter " old fuel filter had no build up", also replaced the engine coolant sensor
can you please help me!
have the same problem?
