OBD code P0441B
Okay at first my car was misfireing under load and throwing misfireing codes. After a while of me ignoring this the SES light went off and came back on as a P0441B which is Incorect System FlowDuring Purge. Now the car is runningfine but throwing this code. I also noticedthat now when i go to fill up inever get the backpressure when removing the gas cap like before. i checked all the EVAP hoses and conections under the hoodbutdid no see anything wrong.Does anybody know where the Charcoal canister is? orwhat is wrong with my car?
Thank you
Thank you

Up to the top and the right, there is a link that says Make a Donation. Click it, and follow the instructions. The seal on the gas cap may be faulty. That's where I'd look anyways.

Had the same issue. The problem for me was fumes leaking from the gas cap filler tube. The end of the tube was smoothed out so much fumes were leaking out.
To fix it, remove the gas cap.
Then get a clean rag or cloth and push it in the tube but do not push it past the flap inside the tube.
Then take some sandpaper or sandpaper sponge and gently rub it in around the lip of the gas filler tube for a few minutes. This will make the lip rough which is exactly what you want.
Afterwards, use carb spray to clean up the filler tube area, carefully remove the rag/cloth and discard.
Replace the gas cap.
Clear the code and see if it returns. If you don't have a scan tool go to AutoZone and get the codes cleared, let them know what you did.
Hope this helps.
