Which light is it? There's one with the outline of an engine (Service Engine Soon) and one that's an outline of a car with a wrench inside (Service Vehicle Soon).

Did you replace the gas cap because it was worn out?

Did you get the new cap from a GM dealer? They should have asked you if the flap inside the fill opening is metal or plastic.

I replaced the one on my '04 because it wasn't clicking anymore (no lights). I bought one from Autozone. Both lights started coming on the next day. After buying one from a GM dealer, both lights eventually went out, and they haven't been back on since. The code was P0455 - large evaporative leak. The Service Vehicle Soon light can only be read by an advanced code reader, such as the GM Tech II at a dealer.
