Just like the title says my 1993 Mustang Lx will barely idle when and if it cranks at all. No throttle response at all. Replaced fuel pump has 42 lbs at the rail, swapped distributors, swapped computer, swapped MAF, checked all fuses. I was upgrading car to 30 lbs injectors and meter and the car was running great went to try out new upgrade and less than a mile into it the car shut off. Trailered it back home and have been scratching my head since. Swapped the injectors and MAF back to stock and still no throttle and will barley idle if it starts at all. PLEASE HELP!!!!
