I posted this in the general section thinking it was gxp do this is a second post. I was driving today and got a cel. Pulled those codes. I pulled the plugs and this is what they all look like. Only have 39,000 and the car runs fine with a little rough idle at times. Battery tests at 13.5 volts so it’s not that. The radio just started going blank a couple weeks ago but still plays fine and it will come back to displaying everything at times. It has come back in the last few days with no problems. I also cleaned the MAF sensor and replaced the plugs for the hell of it. $38 and 25 minutes of my time is no big deal. I drove it for 15 miles and 20 minutes or so. The cel flashed five or six times and then went away and didn’t come back on before I turned off the car. I also threw in a bottle if fuel system cleaner after seeing another thread where they had bad carbon build up on the rings. I’m at a loss. Strange that all 4 cylinders have misfire even though the car runs fine. Always use 93 shell, never below 1/4 tank. Any help would be greatly appreciated.
