Washed my KJ last night, ran fine. Went into work today and when I was leaving it started to idle rough, like it was missing. About 30 seconds later the Check Engine light came on and I shut it down. (I was still in the parking lot). Left it at work and I'm currently driving the shop truck. This has happened before and after getting it in to the dealer for diagnosis, $265 later I was told that water had got into one of the coil modules and the removed and dried it out, and cleared the codes. My choice is this... Buy a $100 OBDII Code Reader and find out which cylinder is misfiring and fix it myself.... Take it to the dealer, have them just read it and still do it myself.... Or just have them do all the work which at $115/hr for labour could be pricey. Opinions? Anyone have this problem before? |

Well you either have a cracked coil housing since since they are expoxied sealed,or you have bad o-rings/rubber boots on your coils.Save yourself some hassle and get 6 new coil packs(like $22 each) and be done with it.

Im curious how just washing the jeep gets the engine wet? Are you washing the engine too? Pull the codes using the ignition trick. I would say it will dry out after driving it, unhook the battery and clear the code. |
