The dealership called today and said they had the new car in early, so I went to napa and got the coil pack from them ($169 with tax) .

I put the new coil rail on and it's fixed now! Thanks to everyone for your input and prompt response. The coil pack I got from napa looks exactly the same as the one that came off the jeep, the epoxy is the same color even, and the numbers stamped into the plastic are almost identical. If anyone wants the old pack for anything, you are welcome to it, I will wait about a month or so till I throw it out, not sure what you could use it for unless you want to hack it up and maybe make a bracket to mount the coils on seperately and then not have to replace 3 every time, im sure 99% of people who have them go bad would just replace the whole thing, but if you could use the good ones off of the bad rail, it could save some people some money (that is if you can wire up the coils individually after getting them out of that epoxy crap). Or you could possibly use it for diagnosing, in that case, this one has a dead cylinder on #2 lol, again, thanks for the help

that is right, and the only place I can find around me that knows what they are talking about is napa and they are $160 from them, not even sure that's what's wrong with it either, sucks because it's just over 200mi out of warranty... I dont know anyone else with one of these jeeps.... thanks for your input everyone, and keep it coming, I have a little over a week until I have to take it back to the dealership for the 11th time....

1976cj5 Yup, sounds like a coil pack, but they can't be swapped as they are sealed in a pack. You could also disconnect the connector on each injector with the engine running. If that cylinder is running, then you will notice a difference when you disconnect it. If you disconnect one and there is no difference then that is the cylinder that is missfiring. You should have three coils for 6 cylinders 1 and 6, 2 and 5, and 3 and 4 fire at the same time. If the coil is bad for cylinder no. 2, then cylinder 5 should not be firing either. Same problem I'm having with my friends 2002 Wrangler. We installed a new coil pack and it still having problems. The new coil pack reads 15k ohms between plugs...as it should. The old pack has a shorted coil, and we are coming to the conclusion that it zapped the brain since it is still acting up with a new coil pack. Hope this helps!!!

Luda dead coil pack, id swap the pack from a known good cylinder and see if it starts working, if so, then you have your culprits.

Cylinder 2 misfire dead cylinder plenty of fuel

Problem fixed now! bad coil rail pack



Hello, I am just trying to get this thing running so I can sell it, I have had a very bad experience with this jeep from the get go. It has a #2 cylinder misfire and that cylinder is completely dead, I replaced the plugs and did a compression test and that's fine, still has a misfire, when I pulled the plugs out, three plugs were gapped at .048 and the other three were gapped at .055 and the number 2 cylinder plug was wet with fuel, so I know it's not fuel related. *I set the gap on the new plugs at .035 and they car copper plugs.* The jeep has 34,249 miles on it, yep, fresh out of warranty. If anyone could point me in the right direction, that would be great, we ordered a new car and it will be here the end of next week and this one is getting traded in on it. It is a 2005 Jeep Wrangler Sport 4x4 with the 4.0L engine with the automatic transmission, any help would be greatly appreciated
