No what is the best way to check that? It may work for a few days before it shuts off. Then it starts right up.
What would cause cyl 1,3,5 misfire. I put oem plugs. Checked gap. Doubled checked new wires to make sure they were not crossed. Someone told me my pcm could be bad causing the shut down, could it also cause the misfire
they are correct. before replacing the pcm on a whim, i think you need someone to scope the crank sensor signal, distributor, and injectors.
if the pcm is bad, you need to find the reason for the failure. if you dont, then the new one can fail as well.
