Default Evap leak small
Looking for suggestions to where to start, my cel light comes on (evap leak small p0442) and stays on, if I reset the light it doesnt come on for 300-400 miles but if I dont turn it off it stays on. It seems most times it comes on if I rev the engine at all. Should I just replace the canister and the purge valve?
