I have a 94 GT 5.0 with the CHP 347 stroker kit. When it first started acting up it would skip under full throttle but it was rare. Then it became more comman and then it got to the point that under any quick throttle it would spit and sputter badly. But the whole time it has done this under partial throttle it runs fine. Now the car won't even start. I have changed the fuel filter, plugs, ignition coil, and distributer cap. The car has good fuel pressure. I don't know what else to do. Any help will bw appreciated.
