Refueling issue

Years ago I changed the fuel filter. Since then when we fuel up we either have to hold the brake and raise the rpm`s to get it to move without stalling or sit for a bit with the rpm`s raised to between 2,000 to 3,000 rpm`s to get it to idle without stalling. Once it moves and drives it will start and run beautifully until we fuel it up again. The local Hyundai mechanics have no clue. We know several owners with this issue so there must be a TSB or some notes on the subject. Any ideas?

Good evening.

The issue I found for this is the canister back at the tank fills up with fuel after fueling it full. Then you try to start it the purge valve sucks raw fuel into the intake and floods the motor. Once you burn off all the excess fuel, it is good until the next time you fill up.

So even though I do not need to hold the pedal to the floor you are coming up with a flooding issue. So what is the fix? And where exactly is the canister and what is the official name of the canister? I would like to correct this issue so my wife can take trips if she likes without fear of having to stop for fuel and not getting the car going again.

In the cars that I had this issue, I replaced the charcoal canister and the canister purge valve. Every car is different. I would have some verify this before assuming it is the issue. This is based on my experience repairing cars for over forty years.
