After replacing my thermostat (3.1L V6), the CEL came on when starting the car to return home from work (got there 20 miles away with no indicator light). The only thing I can think of to cause it was I broke off a fitting on the idle air control valve. I repaired it and it should not leak vacuum. Runs fine. However, the CEL light has not gone off and I have driven 15 miles over a couple of days. Will it eventually sense the problem is corrected and go out by itself, or do I need to reset it?
I have not had the code read because none of the parts stores will do it here in California, including AutoZone.
