Hey guys, I have a 2006 Charger SXT 3.5L HO and recently I have gotten a code for Cylinder 5 misfire (P0305) and now it is starting to idle kind of rough and even shake or shutter after I come to a stop at an intersection. I changed the spark plugs (#5 was more worn than the rest) and swapped coil pack 1 with 5 (since 1 is much easier to get to in case it was the issue). Well after the spark plug change and coil swap the misfire on cylinder 5 is still there, so I know it was not the spark plug or the coil pack. I have run fuel system cleaner several times recently and even tried premium fuel and it is still running rough and shaking at idle after I come to a stop. Sometimes I even hear a knocking noise with the shaking. I am thinking I am going to have to take it in and have it looked at since I have run out of ideas. Has anyone else had anything like this happen? and if so what was the cause? any information would be greatly appreciated, thanks!
