I went here on my way to Tucson , one of my spark plugs shot out of the engine and destroyed the coil also. It was at the end of the day at Litchfield auto repair , originally they told me they didn't know if they would be able to repair it until the following day. They were able to get me back on the road for my bicycle ride in the El Tour de Tucson. I would like to personally thank Mike and Greg for your outstanding service. I was driving from California to Tucson and didn't know what to do. But they totally took care of me thanks again. Mark Griffen
