Hey all, just got my new to me XJ on the road. It has a check engine light for P0301 cylinder 1 misfire. I've changed distibutor cap and rotor, plugs and wires, checked for vacuum leaks and seafoamed it. The PO apparently put 4 hole injectors in it but i have not verified the part numbers yet. The misfire is mainly at idle and just barely noticeable. Does not seen to be effected by engine temp or any thing else. Power seems fine, and i havent driven it enough to see what fuel economy is. Hopefully if my MAC took guy pulls through ill be doing s cyl leak down test tomorrow. Any insite would be helpful.
