I hope this is not a problem but I don't know if it is anything to start to worry about yet. I noticed my Check Engine Light pop on twice so far and only for about 2 seconds and then go off. I did not feel or see any change in the car. Is this someting I should worry about. Anyway to check to see why it came on? It appears it came on when the car is cold. ( only within the first few minutes of driving). The first time it came on it was for such a short time I thought that maybe I was seeing things. That was about a week ago. and it happened again this morning.
