Default P0441 Incorrect Purge Flow

Long time lurker and first time having to actually ask a question. Usually I can find an answer, but this time I'm not certain and I don't want to just throw parts at the car.

History: I've had the car for almost 4 years and have driven less than 2k miles in it. Currently has 132,xxx
Since day one when I put fuel in it, it took several seconds to start it and it would run like crap for about 30 seconds or so and then clear up. It did this every time I put fuel in it. It's also unlikely that I've ever topped it off. After this happened a few times I just started leaving it running while putting gas in it. Ran a bit weird while pumping the gas but acted fine afterwards. Not once did I ever get a code.

8 months ago I left town for Alaska and the car has basically sat in the garage. My kids would start it about once a month or so and sometimes drive it around the block. I had put a couple cans of sea foam in it before I left. When I got back last month it had an smg problem (GPS sensor) which I fixed.

Symptoms: I drove it to the gas station, put 20 dollars worth of 93 in it and then drove a couple miles to the car wash. When I started it back up the CEL came on. Seemed to run fine though and so drove it 10 miles on surface streets. When coming to a stop it had an erratic idle and then died. Started right back up and idled/drove fine. I pulled over and pulled out a cheap scanner which gave me the P0441. Cleared code and drove home. Car died 3 more times coming to stops. The next day it happened again and as I pulled into the garage it died and a light telling me that gas cap was loose, or something like that came on so I went and bought a new cap at autozone because the stealership was closed. Cleared code. Next day the same code so I pulled out the laptop and fired up GT1, which said: E8 DME: Function check, tank-venting system. Was going to see if I had bi-directional control of the purge valve but never got to it because I had found a random USB stick in the garage clutter and decided to see what was on it. Turned out to be USB Killer and fried my computer (damn kids). Anyway, I pulled the purge valve and did a resistance check and got 26 ohms, which I think is good? Not sure how to test power to the valve though.
So then I made up a smoke machine. When I first turned it on smoke came out a vent tube that is vented to atmosphere. Is that not supposed to happen? So I then blocked off the vent tube and found no leaks.

So, unless that vent tube, which comes from the charcoal canister, isn't supposed to vent then I'm assuming that it has to be the charcoal canister itself is bad? Or I have no power to the purge valve? But that doesn't make sense because it must be opening and that's why the erratic idle and dying from too much fumes?

I know it's a lot of disjointed writing, but I'm trying to include everything I can think of...

Oh, I almost forgot, I also put in a new fuel sending unit, but that was like on the second day, after it had already coded.

Anyway, any thoughts are appreciated.

I'd replace the fuel pump...

Actually, the previous owner had changed it a few months before I bought the car, so it only has a few thousand miles on it.

Replace the purge valve, unless I missed you saying that you did. Classic symptoms you are describing of the crap idle after fueling up, not to mention you have a code for it....lol be grateful you have a code instead of chasing things without one. You can pull on off any E46 basically at a junkyard or just buy a new one. I got one for 9 bucks off a 330.

Just had my purge valve go as well. Threw the patent air flow code.

Thanks for the replies fellas.
I checked the purge valve with my ohm meter and got 26 ohms so I thought it was good, but they're cheap enough that I'll buy a new one.

Also, the check gas cap light came back on again last night. It's not loose.

And now the check gas cap light won't go off. lol this is more difficult to figure out than the SMG.

If the purge valve is stuck open it probably will throw this code as it's basically a leak in the fuel system.

So you made me go back and check the purge valve and sure enough it's in the open position.

Checking its position never crossed my mind after running an ohm test on it. I assumed that meant it was still good.

So thanks everyone for the replies. Hopefully I'll get the valve tonight and update the outcome.
