I have a 1966 Mustang Convertible Restomod, with a 1992 5.0 rebuilt(2/07) .030 stock piston, stock heads, mild erson cam, 65mm throttle body, A9p computer, rebuilt AOD with shift kit and b&M torque master 2400 stahl, 150lph fuel pump, cobra intake, 19# injectors, 1 5/8" headers, stock distributor, ford racing coil, ford fuel injection wriing harness, 8" 380 posi.
The car starts and idles fine, runs up to 3000 rpm and it starts sputtering and back fires, I have changed computers, distributors, modules, wiring harness. I have checked timing and tried advancing timing with no luck, it seems as if the distributor starts to retard as the engine rpms climb. HELP!!!
