If you remove the valve from the canister and look into its port the hose attaches to I am willing to bet there is rust on the pintel inside. The only real way to fix that is to replace the valve as it drags every time it operates and will not close all the way.
That is my initial thought, but there are 2 complications to that. 1, even with my VIN and the current Canister part number, no Infiniti dealer around here seems to be able to figure out what parts I need. Second, there was a TSB or something o that effect that changed the parts. Accordig to 2 dealers, the parts on my car were replaced by new parts, bit noone knows the proper parts for my car.
It is more than a little frustrating, because I just want to replace the parts and be done with it.
If I gave you my VIN could you possibly look into the proper replacement parts?
