Car runs fine except when towing 1800 lb pop-up camper. After an hour, the check engine light comes on and the car starts "jumping". Gas mileage decreases. Carbon monoxide detector in camper starts beeping. Disconnect the camper and let the car cool down and it runs fine again. Code is 341 - Octane incorrect or octane adjust service pin open or octane adjuster circuit open - no one can figure out why. Any ideas? Thanks!
have the same problem?
