I think i need to replace a cracked coil. Any thoughts/advice? Anything else i should do while i'm in there? Someone said do the spark plugs and the engine torque damper? my 2004 Cayenne S has 125,000 miles and i want to proactively replace parts as i fix any necessary pairs.

Also, anyone know where i can find durametic scanner code errors? I get error codes1144
