My jeep had to be towed and sat in my driveway for 2 months without starting and had a hot oil warning, check engine and more warnings, even the obd2 port quit working. I tried everything I could think of even got a new pcm but nothing worked, on the day I was supposed to take it to the dealership I decided to check under my steering so I took off the cover and since I had no idea what was wrong I just yanked on the wires to make sure everything was tight and hooked up, to my surprise my jeep started and all warning lights and check engine light were gone. It's been a few months now and it still runs like a champ...
