I have a 1996 Pontiac Firebird V6, and my check engine light keeps coming on. I took it to my mechanic who said the light gave him engine diagnostic code 1441 "purge system." He could find nothing wrong with the car except the service engine light. After a few days, the light came back on again. Does anybody know what this means? It is not my gas cap, I have already checked that. I don't know what code 1441 purge system means. Any help would be greatly appreciated.
