Thanks for the reply. The dealer was very good about getting the car in right away. They said that if the light wasn't blinking then it shouldn't be anything to worry about. They found a small leak in the evap. system. They rechecked it and said that everything was OK. The service guy said that this could occur from a loose gas cap or any number of minor things. I frankly don't understand it all, but all seems to be OK now.
