Tony,
When I first bought my coach (series 60) I started getting CEL and it read "High Temp Fuel Circuit Low" or some crap like that. The light came on and off for about 3 years! Finally, it stopped. It hasn't come on anymore in the last 2 years. I believe that moisture was the cause or planned obselence from DD.
Jon's advice to check the codes is a good one, but all of us have had a CEL blink from time to time and nothing becomes of it.
I always check my oil level, anti-freeze level, and transmission oil level - if those are good I don't worry about it. It usually takes care of itself.
