Well lets see it could be; spark plugs, coil pack, burnt valve, bent valve, head gasket issues, loss of compression, any amount of wiring issues, fuel injector failure, bad pcm, Test all that to start. Hope that helps.
My hemi is missing on the 7th cylinder and the 4th cyl coil is suppost to help with hydrocarbons, this happens when the engine gets hot and when the engine is under a load, Any ideas of what it could be?
