Curious. . . About a week ago and about 36 hours after having returned from Orlando, the wife came home and said the check engine light started glowing when she started up the car after a Zumba session at La Hacienda and some of the auto on/off features (radio/locks/etc) weren't working properly. I was able to get all the auto on/off features working but the check engine light kept coming on steady. Later the next day I remembered that a loose gas cap will often cause the check engine light to illuminate. I stopped the car, removed and reinstalled the cap. Turned off the car and restarted it and sure enough no more engine light. We hadn't gotten gas since two days before our trip to Orlando so we should not have removed the gas cap in a sequence to cause the light to illuminate after our return from Orlando. I wonder now if maybe someone had helped themselves to a bit of gas (tried to anyway) and didn't put the gas cap back on properly. Maybe the possible gas thief doesn't know that many cars (mine included) have an anti-siphoning device included in the filler tube.
