2005 Hyundai sonata won't idle

2005 Sonata V-6 2.7 Liter. I had a similar problem with my car not wanting to start, then dying if I didn't keep the engine raved up, once I got the car moving no more issues until I stopped for gas again. (My issue only happened after refueling, every time) I resolved the issue by replacing the purge valve cost approx $44. I bought the part and a friend did the work. (I think it is located in rear the wheel-well drivers side). If you purchase this, I recommend getting the one with 2 pieces the little canister looking thing & the little pigtail attachment. I purchased the the one piece because it was in stock. Eventually my Check Engine light came back on, even though it wasn't dying on me any more. I was told, I needed that other piece too, in order to keep the check engine light from coming on again. You can not purchase the pigtail part without purchasing a canister. I think the price difference in the 1 and 2 piece option was about $5 or less?)
