My 1995 Jeep Wrangler has a engine miss. I have replaced the plugs, plug wires. It will run find for a while and then the engine will miss. This will happen when it is idleing too. I have had it to 2 repair shops and they cannot find the problem. The computer check says everything is ok, but they say their is a problem and they have kbow ideal what is causing it.
I am currently working on the same problem and have found the wiring pigtail to the ignition coil to be faulty. when the engine gets to operating temp it starts stumbling and dying. i checked the coil pigtail and wiggled it and found it to be the problem on the one I worked on. Hope this helps.

This did not help. Thanks for trying. Could it be electrical
I did that. Thanks for trying
I've owned my 1995 Wrangler since Oct. 1994, and replaced or repaired every component except the charcoal cannister (including two engine rebuilds and one manual transmission overhaul). I have the factory manual on CD. I was driven nuts for 3 years by this exact same problem. After replacing every electrical component except the alternator (including the fuel pump and Powertrain Control Module, PCM) and going to a mechanic's school and learning a few tricks I finally traced the problem down to a loose connection in the back of the pigtail, the plug part. There are no dealer replacements for this pigtail, and I am in the middle of determining if a similar part will work, or if I can remanufacture the one on the vehicle. My diagnosis was considerably confused and complicated by the fact that the rubber drain tube for vent in front of the windshield was filling, (freezing when cold) then pressing right against the connector and also shorting the damn wiring harness out. This is the most likely cause. Every other sensor, control and connection (including the rubber for the vacuum system) had been repaired and not solved my problem.
