Need Help Badly I have replaced the optispark with a dynaspark, fuel pump, fuel filter, plugs and wires, throttle positioning sensor, idle air control valve, map sensor, and the mass air flow sensor. When i start the car it runs fine for a few minutes and then starts to miss...when i drive it it surges badly. The fuel pressure reads normal...i checked all the plugs and wires and they are fine too. Does anybody have an idea of what this could be? The only code it is throwing is the coolant temperature sensor, i replaced it, and it still throws the code.

That temperature sensor is 90% of your problem, trace the wiring all the way back. Did you replace the one on the water pump or head? Replace the coil as well, then look into the ICM.

Yeah i replaced the connector for the coolant temperature sensor to the pcm and no more problems. I'm gonna check the spark plugs tomorrow to make sure that none of them have become fouled.Appreciate the help
