Im assuming its fuel related since it only does it after i fill up. Anyway, i pull into a gas station, fill my car up and go to start it and nothing. It'll turn over but it wont start. Eventually if i keep at it, itll catch and start, but then it wont hold an idle. If i keep giving it gas it will eventually hold the idle. This ONLY happens when i get gas. If i go out to wherever it'l start fine, with no problems. I always use 93 and never run it below a 1/4 tank.

Car is a 99 Ws6

Thanks in advance
