Misfire, no codes

jojo2333 · 06-15-2021, 10:32 AM

Misfire in cylinder 1. Ruled out coils and spark plugs, swapped out the injector for another injector but problem persisted. Gonna try a different injector again tonight. NO CODES OTHER THAN MISFIRE CODE*****

Valve cover replacement tonight because of oil leak, and also gonna check the valves to check for carbon build up while I'm doing the valve cover.

Compression on all cylinders is good.

MHD responded to my log saying it could be injectors and that I have an AFR issue.

I don't know what else to check at this point. I'm hoping maybe I'll find something tonight when I look at the valves.

Any ideas? Check out my log if you'd like
