Need your help here guys. I have an 02 GT with 5/speed. Working great yesterday with 40 miles put on the car until I shut the off the engine briefly. Car started up again and felt like it was misfiring while I drove less than a mile. It continued to misfire then just quit. Felt like fuel starvation. Car still has a 1/2 tank of gas. My thoughts are: 1. Clogged fuel filter 2. Idle/Air control valve stuck 3. Bad fuel pump. Any ideas out there on what this is and how to fix?
