I drive a 2014 Dodge Charger SE with a 3.6L VVT Pentastar Engine. A few weeks ago, I received the cylinder 1 misfire code (P0301). I then replaced all the spark plugs a couple days later and while I was under there, I noticed there was oil in cylinder 3 spark plug well, I cleaned it all up and I also replaced the gasket valve cover seal, the o-rings and also both camshaft sensor seals. Took it for a drive and everything was good. Smooth shifting, no noises. Even checked the spark plug well after and there was no more oil getting down there. I drove it for a couple days and the check engine light came on again. I’m looking to explore if it’s the coil by replacing cylinder one’s coil with another and see if I get a different code. I’m curious if anyone else has had a similar issue and if so how did you go about it and what solution worked best for you? I’m pretty novice when it comes to cars but I’m learning and I have really great guidance assisting me along the way. I just really love this car and want to be able to work on it myself when I need to take care of maintenance. Also get some different perspectives. Any input is greatly appreciated.
