What is your question?

Hi! This is just another question, but important to me. My engine light is on. It went off for a short time (about an hour), then came back on and stayed on. My engine runs great! (187955 miles. Oil clean,plugs new,doesn't overheat, easy starting, power excellent, elect. connections excellent, fluid levels great). What causes this to occur on a regular most often basis for no apparent reason or symptom? THANKS for any advice. I really like this Toy! Bought it about 5 months ago.
