Had plugs and coilpacks changed in my 08 EL about 20k ago... A couple weeks ago she started running really rough. It was right after I refueled at a station I normally don't use so I just figured it didn't like the gas.. Two tanks later it hadn't cleared up but it finally showed a code so I started troubleshooting. Turns out the electrode was missing from the cylinder 1 plug. Changed the plug, problem solved... Ran smooth as ever.
Then this morning it started running rough again and it showed the same cylinder 1 misfire code. I haven't checked the plug yet but I'm guessing it's going to be the same issue. Any idea what might be causing this?
