Well, we got an answer. Remember, the motor started idling rough, then about a day later, the check engine light came on. Guess what? it was a spark plug wire worn through the insulation shorting against a metal pipe, EGR I think he said. The check engine light said it was something causing too lean a fuel mixture. That was not even close. Anyway, we replaced all the spark plugs and wires, and it runs perfectly. The mechanic said it had the wrong spark plugs anyway. Now it has all new hoses and belts, new timing belt, new shocks, all kinds of great updates. Now trying to get the refrigerator to work. Not getting anywhere.
Best regards to all RVrs.
