I have an 09 Unlimited with 16k on it. Saturday as I was driving (aprox 25 mph) my jeep started to sound like shit. At the same time the etc light, esp light and check engine light all came on. When I turned it off and restarted it, I had the same problem and the idle was extremely rough. Sunday morning I start her up, no rough idle and no lights on. Im sure if i bring it to the dealership they will tell me nothing is wrong, since the lights are off now. A buddy of mine said i probably got bad gas. Anyone have any idea????
