ok here's what's been happening: I'll go to the gas station to fill up, it doesn't matter if I have no gas, or a half a tank of gas, as soon as I screw the cap back on, get in my car and start it, i really have to give it alot of gas on the pedal to start it. and when it finally starts, I have to keep it at a high rpm for about 10 seconds or so or it will stall. What the hell? does anyone have this problem or a solution? thanks[/align]

 

I swear I've heared this before somewhere =) Search the forum!
1 on fuel injected cars you don't hold gas while starting, never.

I might be wrong but I will think it could be fuel pump or fuel pressure regulator related, sinse the only thing that changes after you fill up is amount of gas in the tank.

 

My guess is you have a evap purge problem, scan it for codes.

 

+1, just scan it and see what the problem is.
