ses light on

[98gtblue]

Put L/T headers, o/r h-pipe, and mils but still the light is on. I reset it already.
Does the light affect peformance?

The light itself will not affect performance. Sometimes mils don't work. You should have your codes pulled just to make sure that it is an 02 sensor fault. If that light is on for something else and you think its for 02's, it could cost you down the road.

Did you reset the computer after the mils were installed?

If not, disconnect the battery for 15-20 minutes to reset
