We made plans to meet this morning with Fred and Sherry and drive to Sayulita about 20 miles south of La Penita for breakfast. Unfortunately about 10 miles south of La Penita the engine light on the PT Cruiser came on and the engine seemed to lose power. We pulled off the highway and checked the oil etc and everything seemed ok. And when we started the car the engine seemed to run ok except that the check engine light remained on.
We decided not to chance continuing on to Sayulita and turned around and headed home. Fred and Sherry were nice enough to follow us back to La Penita in case the car died. I know how to cancel out the car's computer in order to turn off the check engine light and did that after we got back to the park.
Although there's no shortage of good mechanics in La Penita, I'm not sure if any of them have a computer that can diagnose the car's problem.
