The check engine light (service engine soon) comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on, too. To determine the cause, the vehicle will need to be taken to AutoZone or a shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 scanner, While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area.

I had the same problem, it was the distributor cap, (must have had a hairline crack that i couldn't see). Changed it and the check engine light went out and it started again when it was wet outside, one you could check for is bad spark plug wires. Moisture may cause spark to jump causting misfire.
