Ok here's the story one day I went to replace the thermostat. One of the bolts broke in the intake and I had no choice but to remove the intake and replace it with a juke yard one.I got it all together and running,temp is running good. But there is a miss around 35mph almost like a plug.SoI replace the wires plugs and cap. Still no fix. The truck ran great before all of this. I ran the codes and there good. I also checked the fuel pressure it is 32psi running and 40 with the key on engine off. When you kick it down to pass Etc it runsgreat but when at a steady speed 35 3rd gear it jerks bucks and misses. I checked everything even cleaned the injectors. The truck ran great before this and never got hot. There is no coolent leaks. I don;t know really were to look now. I even replaced the TFI. I just don;t know what went wrong. anyone know where to look?? I think the intakr came of a 93 302 it bolted on great same thing as my old one.
