Question about 2003 Oldsmobile Alero
Well if you bought a good gas cap and the right one you need to check for a leak at the evaporative lines check the pcv valve and for any vaccum leaks if that is not it you could have a bad evap vent selonoid or bad charcoal canister. it is a simple diagnostic if you had a scanner and a smoke machine.

The first two were not listed in the file that I have, the third has to do with evaporative emission control has a small leak. The first two seem to be other codes having to do with the same area. Check the hoses and fittings at the fuel tank area for leaking or damage for the vent system. Check the fuel entry to tank hose and fittings. Locate (underneath the body) and check the charcoal canister for cracked case, loose or damaged fittings. Clear the light with the scanner and see if other codes show up. Are there any obvious problems other than fuel vapor leaks?
