Hey guys, been having this code go on and off a few times and not sure what's triggering it... Is it best to try and replace the purge valve solenoid first? I believe I do have an exhaust leak by the exhaust manifold, but to my understanding, the exhaust has nothing to do with the evap system... any insight will prove valuable... thanks!

Okay so it looks like the evap system consists of the vapor solenoid valve, and the purge solenoid valve...

i already have a vapor solenoid valve, so i'll try to replace that first under the car...

if it doesn't work, i'll try the purge solenoid valve under the hood

if both don't work, i'll probably have to get a smoke test, since i read somewhere that the charcoal canister almost never can go bad... and also i suppose it could be a vapor line leak...

keep you posted :D
