Have a 2006 300 Limited, v6 3.5L. Experiencing a misfire with the code P2311. I’ve recently changed the spark plugs and coil #4 which i found melted and im still getting that code. The car shakes abnormally when it starts. I also realized the wires in my ingition coil connecter thats linked to that coil are jacked up as if the previous owner been messing with them. I owned the car for 2 1/2 years and never experienced any real problems till now. Any advice ?

 

where is the oil coming from ?

 

Its coming from that same bad coil. I want to believe its because i havent changed my valve cover gasket since buying the car. Which i just did yesterday. Just didnt have it installed. I havent been driving my car at all since recieving the check engine light
