Replaced O2 sensor.....

and the car is now running great again. Only problem is that the check engine light comes on while sitting still (stop light or sign). Then goes out when I start moving. Do I have to reset anything? Any thoughts or info would be appreciated. Thanks

Chuck

Shouldn't do that.

Perhaps pull the batt. wire for a few minutes to reset? Just a thought.

Disconnect the battery like Repeater says. If the light comes back, you need to pull the codes.
