2008 Chevrolet Aveo Q&A
2008 Chevrolet Aveo Question: engine light on.got it checked said a small emistion leak.do i need a mechanic?
To find a leak in the fuel tank, fuel lines or charcoal canister a repair shop will use a "smoke machine" that generates an inert gas that locates the source of the small leak, or they may use a vacuum pump to test valves or even a scan tool to close valves and test them. Nothing you can do yourself. - patrick mannion
yes, you better call for the help of a mechanic. - chinasinoy
