The Service Engine Soon light came on in my 2000 Silverado (100,000 miles).

I checked the gas cap for tightness, filled up with high octane gas, and poured Injection Cleaner in the tank.

I'm ready to take it into my mechanic, as the light remains on after 50 miles. But he says you need to reset the computer (after doing the work) for the light to go out.

Anyone kow how to do this?

Thanks in advance
