When I left this morning to take the car down to the dealer, my Check Engine light was no longer on (of course)! I took the car down anyway, and they suggested waiting to see if the light comes on again. They said it might give them a code now, but I would be better off waiting until the CHECK ENGINE light was on for testing. They asked if the car was running any different with the light on (to which I answered no), and they said that it was most likely an emissions malfunction. I guess we'll have to wait until that CHECK ENGINE light comes on again?!!?!?!?!?
