Thank you sir. I'll suggest all of that to my mechanic and hope for a find.

Moses, I've read through the 4.0L Jeep Six: Cylinder #1 Misfire Trouble Code discussion (and a couple of others related to it) and clearly you know what you are talking about. For this issue, my jeep went into a mechanic (I'm good with horses, not vehicles) and the following has been done. Full tune up including new sparks and wires, new bank of injectors, new coil. None of that fixed the problem. As far as symptoms go, my Jeep is a 1999 Wrangler TJ with 180,000 miles and cranks relatively easily and will idle a bit rough. There is a miss you can feel that is intermittent and has never been "bad" although seems to be getting worse lately. No burning oil or smoking and when spark for cylinder one is pulled it is dry, so no oil backing in. The only other symptom I feel is that my Jeep seems a bit "under powered" at times. What would you suggest as the next thing to check for my mechanic? I'm hoping to stop buying parts for trial and error--the old retired and fixed income stuff has a hold on me. Ace
