I'm having a problem with my first-gen, a 1993 XLT. It just keeps dying whenever I am idling at a stop for a while, it doesnt happen all the time though. The engine will spudder and it feels like it is tryin to move while im on the brake. It then dies. Now this usually happens when I am below 1/4th tank but it recently happened at 3/4 tank. Every time it dies it starts right back up though. Any help appreciated.
