Ladies Blazer --

The reason is probably with a layer of gas that needs to be replaced, or not properly tightened after the completion of a check or smog.

On the restart, you can disconnect the battery for 10 seconds, then the cables. This should clear the light. If the light is on again after you replace the battery cable, then you need to leave Chevrolet and you can start the computer in your vehicle.

Tell them the appropriate restoration procedures, but he had a few different ways, your work, and if I invested my vehicles, which cost a new computer, and do not in my hands, and I sincerely believe that you do not want to buy a new computer either.

Safest bet is to disconnect the battery to connect, when the lights go out, then you are are good, if not head to Chevy, which entitles him.

Good luck!

Disconnect the negative cable from the battery for 15 seconds. This will reset your ECM.

I had the same problem with the same year, make and model. In my case, the O2 sensor is EXHUST in the pipe.
