Engine Mechanical problem
2001 Toyota 4Runner 6 cyl Two Wheel Drive Automatic 156000 miles

I see these codes are related to an emission leak and control circuit malfunction. I ran 2 bottles of engine cleaner - the kind Advanced Auto recommended, not the $1.99 stuff - and changed the gas cap. The dealer says I need a need Charcoal Canister. Does this sound right? Gas mileage is starting to decline.

Do you
have the same problem?

No
