My car has a hard time starting after I get gas. It does the same thing every time. It tries to start after a couple of cranks but then stalls. Then it turns over for a while before it finally starts but then runs rough. The engine will finally pick up RPMs if I hold the accelerator down. It kind of sounds like its flooded and then it clears.
It only does this when I get gas not when I stop really quick at a store or something so I'm thinking it has somwthing to do with taking off the gas cap.
