97 XJ Cylinder miss #1--stumped
Hey guys/ladies, I have a 97 XJ with the straight 6 of course. well I've been having a cylinder 1 miss for quite awhile. I am an at home DIY mechanic and I must admit this has me stumped. I've replaced the cap, rotor, spark wires, Spark plugs, injectors, ign coil, new upper block gaskets. at this point i'm just leveled. I put over $700 in the past few months into my girl (granted at 231k alot of it was preventative maintenance). The only other thing I can think of for the misfire is bad valve, bad rings (doubtful, no smoke or elevated oil pressure), bad timing set. I'm basically looking for some input you guys might have into a new direction I can look into.
