About 2 months ago my Envoy out of the blue flashed “low oil pressure” on the dash and the engine cut off while driving. I was able to get it pulled off to the side of the road. Although it was idling roughly it did crank back up. I put my OBD II on it and got several misfire codes. In fear of harming the engine I had it towed to my Tennessee home. I replaced all 6 ignition coils as well as the 6 spark plugs. The car turned over and fired up but still read a misfire on cylinder 4. I pulled it back apart and found oil. A few days later I was going to have it towed to my Atlanta home as that’s whew my tools are and it was completely dead. I jumped it off, drove it on to my tow dolly and let it run, so to charge what I thought was just a drained battery. Got it home and of course it was dead again and had to be jumped off to get off the dolly. It has since then been on a trickle charge but will not turn over and reads “Unidentified Driver” when turning the key on. I am stumped at to what’s going on. Any ideas what I need to do to it in order for it to begin turning over again? I’ve taken the battery loose and hooked it back up and it reads the same “Unidentified Driver” on the dash and misfire on cylinder 4 on my OBD II… this is my baby and I want her back on the road. If anyone has any suggestions or knows the underlying problem as to what could be causing this please let me know. I work on all my vehicles personally and over the years have never ran into a problem like this. I’m self taught so I’m no pro but I’m definitely able, willing and accepting to learn what I don’t know.
