Hello first timer with this forum and first timer owner. I have a 2001 Volvo S60 T5 and recently acquired it. I knew the camshaft position sensor had been bad and so replaced it. It runs a little rough still and I had put my OBD II scanner on it and the code p0305 cylinder #5 missfire. Has anyone else had this problem and what have you done that has stopped this problem from coming back?

 

Coils are a fairly common failure. Swap the #5 coil with another cylinder and see if the misfire follows the coil.

 

OK, thank you I will have to try that
