Gas?

Hello,
I have a 2000 Hyndai accent with (roughly) 90,000 miles. It's a manuel 2 wheel drive. Recently (w/in the past few months) when I get gas regardless of whether it was empty or partially full when I fill up I can't start the car again without revving the engine. The same thing happens on a cold morning even if I let the engine warm up for a while. After I get it to go it lurches for the first few minutes. I had the exact same car, same year, and purchased within 2 weeks of the one I have now and it did the same thing. With that car I had no money to do anything about it (not that I do now) and it got so bad that it never stopped lurching even on the highway. Do you know, perhaps what it is, or where I should start?

Thank you for your help!
Melissa
