Purge Valve replacement

Disclaimer: I know very little about cars but would like to remedy that.

My car -2005 Accent- wants to stall immediately after filling the tank. Only then. And only for a few minutes afterwards. Once I have my foot on the gas pedal for a bit, it runs perfectly fine.

A P0711 code came up last week and I brought it to a local transmission place. I explained the fuel issue and they had no ideas. They replaced the trans fluid temp sensor, gasket and filter as well as spark plugs and wires (I was in need of those last two). The CEL is gone but this issue still remains.

Poking around on the forum here, I see that a common problem that would cause this is a bad purge valve. Is this possibly something I could do myself or is it best left to someone with experience?

Thanks~

Yeah that is the typical symptom, should also be a ECM code showing up as well.

Gas tank evap,has an air inlet filter close to the tank fill up spout that can also cause refuelling problem start up.

Thanks santa. There wasn't an ECM code that I know of. Do you think this problem could be caused by something else?

I just watched a YT video for replacing it and it looks like it is pretty straight forward to do. <famous last words>

It is easy to change and I have had them fail before; but there was always a code.

Without code I would guess the tank air filter, which happened to a 2005,élantra we had.

Don't spent the money yet!
Remove the purge valve and wire it to your battery to see if you hear it clicking and blow through it as well.
If you need one? only buy an original because it will NOT run correctly with your ECM computer.
Many codes from a bad DM-TL or gas cap or rotted tubing from the filler tube.
If your charcoal canister is breaking apart and jamming the DM-TL let me know.

Thanks for the additional info, jimbro. I will take your advice with checking the purge valve directly off the battery and see what happens.

Also... I always "top off" a full tank of gas. Every time. *hangs head in shame* I had no idea that you weren't supposed to do that. Lesson learned.

i wouldn't even bother taking the time to connect to battery, usually these problems are the valve sticking open. normal operation of this valve is to open and close quite rapidly once the car has been running for a minute or two. even putting your finger on it it's quite obvious. the valve is rather loud, very normal for it.

to check for passing (ie. stuck open which sounds like your problem) just take off the tube on the passenger side (other side goes into intake, you want the long one) and attach a piece of CLEAN tubing. now blow into it. you'll know if its stuck open and passing right quick.

I had the purge valve replaced and the problem with stalling after fueling is gone.

But the new purge valve makes a very loud clicking/vibrating sound. I understand they supposed to make a clicking sound, but this is very loud and its never sounded like that before. Any suggestions?
