I have a 2008 Ram 2500HD with a 5.7 liter Hemi engine. The check engine light is on and I need it to pas inspection next month. I know the code indicates a "multi-cylinder misfire" but the truck starts right up and runs great. I've replaced the plugs, fuel pump, and the crankcase positioning sensor but the light stays on and the code 300 still reads. The truck does not leak coolant so I don't believe it's a head gasket problem. Any ideas?
Thanks,
Russ
