P0300 P0305 Spark Plugs and Spark Plug Wires
Just a little info in case anyone else has the same symptoms and error codes. 2002 C32 with 117K miles. Started idling low/rough when in gear and stopped and a bit in neutral/park too. Codes came up: P0300 (Random Misfire) and P0305 (Cylinder 5 Misfire).
Dealer wanted $80 for EACH spark plug wire (we have 12).
I bought the SAME exact BOSCH OEM wires online for $100 shipped, yes that's for ALL 12. Even came wrapped in the same OEM plastic baggies with OEM part numbers.
Bought 12 new NGK IR plugs online.
Cured the rough idle and cleared the error codes. I would say this job is completely DIY for anyone.
