it is worse on gas, it is harder to start, and can't fill gas tank, pump keeps shutting off, replaced the vapor canister ven valve solenoid, because i was told that was the problem
Customer reply replied 3 months ago
also the codes are po449

O.k.,what can happen that I have seen several times in the past before is the vent valve can fail and causes dirty to enter the canister.The valve is replaced but the canister has become restricted and I have had to replace the canister as well to correct this issue.

I would make sure the vent lines from the fuel tank are all o.k. and if they are then I suspect the canister needs replaced as it will cause this fault here.
