So I have been dealing with a misfire in cylinder 3, which the mechanic says it has very low compression but didn't give me the numbers,
but I checked compression before the shop did, and all cylinders show 180psi this was before and after I had the head off for a valve job. The misfire was present before the valve job, when I put everything back together still same misfire, I have checked and tested just about everything Im leaning towards EGR stuck open? because with vacuum applied the engine does NOT STUMBLE or stall but would that effect only one cylinder?
