P0452 Pontiac Grand Am GT 1998
The only real symptom is smells like gas real bad sometimes, and the check engine light. Where to start?? Put in a new AC Delco fuel pump a few years ago, and was fine until last year during summer. Started smelling gas real bad, every few cycles the engine light will turn off, so maybe I have a bad purge valve or charcoal canister?? Any help would be great.
