The check engine light just came on as I was doing my coolant flush. Here is what I did:
1. Drained the coolant at the radiator plug on the lower side of engine.
2. Ran water through system with car off and the plug off.
3. put the plug back in, ran water into the system and topped it off, started engine til the thermostat opened.
4. Drained the water out.
5. Put the plug back in and added coolant, started car, and as the car was warming up the check engine light came on
Any ideas? did I do something wrong? I have to drive home to go to work (i'm out of town) and i really need to figure out what happened, please help!!!
