Whatsup! Recently had a Sc400 with the V8 come in trying to get this Evap Code to go BYE BYE!! LOL and found that its only throwing a P0441 incorrect purge flow. Now I have an idea of whats going on im think Charcoal Canister and VSV but not sure how to distinguish the two if one is working and the other isnt. I know I can apply Vaccum and possibly find out if theres a leak or insufficent flow but the incorrect purge is what gets me. Can someone help?
