I have a 99 Regal GS. Lately I have gotten the Service Engine light with the these codes. So far I have replaced the sparkplugs, wires, and today the coils. When I replaced them to today and disconnected the battery to reset the ECU, afterwards when I started teh engine, there were some weird sounds coming out of the engine bay. Something like a spark jumping. I'm all out of ideas. Another thing that could be wrong is the grounding of the car or the crank position sensor(which is impossible to get to. Its behind the main pulley that drives all accessories.) Ha sthis happened to anyone, I really need help, I reallly dont know what else could be wrong. And I hardly think that the problem would be in teh crank position sensor....HELP
