The check engine light (called the Malfunction Indicator Light) also comes on at specified intervals like 60K, 80K, 120K, and 160K miles (hopefully so you'll take it to dealer to get it re-set, and they can try to sell you service and timing belts, etc.). If that's the reason, two wires under the dashboard, extreme driver's side must be swapped, then swapped back the next time this happens.
