In normal operation the engine light came on. Went to AutoZone and they ran a diagnostic check and told me the gas cap was bad. I went to the dealer who did not hurt me to badly, replaced the gas cap which took all of two (2) minutes and drove the car. The dealer told me that the light would go off after 15 cycles (starting, driving, and cutting the car off). Seems like it took forever for the light to go off but it finally did. The car just turned 100k. - Visitor
