I just bought a 2004 Jag x-type, I have a3 cylinders misfiring Codes P 0300,0301, 0303, 0305 as well as P1313 indicating catalyst damage,If I continue to drive without changing the catalyst right will that damage the engine?
The misfires causing the raw fuel to dump into the cats will eventually clog and or damage your cats. So change your plugs and the coils, specifically 1, 3 and 5, but since your in there replace all. I would assume the cat codes will go away if the damage isn't already done. How long where you driving with the CEL on and the misfires?
