If 1 cylinder has a 30PSI reading and all the others have a 150psi.
Question
The cylinder with the 30-psi still have enough compression to fire and keep the engine balanced, at this point the engine is running as rough as if a spark plug wire was disconnected. Any suggestions
Please note this is a GM 3.1 V6
