A/C delco plugs put in today gapped at .60, no fix...Next task is replacing the camshaft position sensor...Maybe Monday or so..

You could buy a modded one for around $100 and send them yours. Should all work out as they will flash your old one anyways.

Im thinking on trying a pcm, Rare they go but always a chance for sure.

Tonight I got a pending code for cylinder 4 misfire P0304, Guess I know what cylinder I will test first.

I bought a compression tester today so I'll be able to rule some stuff out
