Wiring harness that goes behind valve cover is melted. I have had to have my 2003 jeep grand cherokee's # 3 injection wire replaced twice. Once before 70,000 miles and again within the last year. While it was still under warranty the vehicle would spit and sputter and I'd smell gas. The vehicle would stall. The facility changed the #3 injector and it ran okay for a short time. It did it again and "something else" was the problem. Traveling after the first 'fix' and it bogged down, heavy gas smell, hesitation, etc. The #3 wire replaced. A little over 1000 miles to next destination and it took 4 tanks of gas, horrible smell, spit and sputter, etc. Limped into port, #3 wire and injector replaced along with a tuneup for fouled plugs. This year it happened again. Took it in and was shown the wiring harness is melted. #3 wire replaced. This has been costly and even though the facility sees the melted harness they haven't questioned why. Is this a fire hazard waiting to happen? I'm not sure of the dates but can hunt done paperwork if needed.
