Re: Any mechanics out there?
Go to an Autozone or Napa. Tell them what is going on and that you suspect it is the fuel, and that your roommates car is doing the same thing. Throw in that you suspect that someone messed with your fuel. They can set you up with the proper additives, and or point you in the direction of good local mechanic that can drain your lines and tank. You should probably get new filters again after this. Get a locking fuel cap.
Whenever you get mad over a called strike or ball on a close pitch, it's the equivalent of being mad at the QB pump-faking one time before throwing a pass in your average NFL game. ---Caveat Emperor
