not sure if this helps, see if the gas cap is bad.
there is no fuel in the charcoal cannister. only vapors. where did you come up with that?As for the rest of the symptoms, unless the Evap purge is being enacted when the motor cannot manage the extra fuel stored in the charcoal canister under the car (hot start, idle, etc.), or it is stuck open all the time then I suspect they may not be related to the P0441.
the blue connector goes to the butterfly valve in the stock air box. the black connector is for the EVAP purge VSV.
This is the same issue I had when I first bought my car from the dealer. They replaced the charcoal canister, fuel cap, etc. and it was this simple thing that was throwing the code the entire time. Still get it from time to time but it might be time for a new cat. Passed emissions just last month so I'm not sureIf that's all that's caused mine you will surely be my heroes because now i don't have to drop the tank. Blue was on vsv and black was on the box, lets see if the light stays off.
