2001 Chevrolet Venture LT 6 Cyl 3.40L

Engine

My Service engine light came on, I had it checked, the mech said it was in the exhaust, or 02 sensor. he cleared it.

a few days later i Hit a rough spot and it came on again. He thinks it is the Vapor canister. If that was bad wouldn't it be bad all the time. I think it could just be the gas cap, its 10 years old. What do you think?

Ask your mechanic if your vehicle has a CAT sensor?; it will be near the catalytic conv on the engine block (underneath)
