This is a 86 ford ranger xl with a 2.3 non turbo fuel injection engine. The vehicle starts to to miss, stumble and loading up and then you have to feather the fuel constantly. This happens when the vehicle reaches operating temp. Never does it when it is cold. Module, cap and rotor button fuel pump, fuel filters, temp sensors all have been replaced, but still does it when it gets up to temp.

Have you checked things like the catalytic converter (plugging), fuel pump pressure?

Wow, you've done a lot already. I assume since there is a new fuel pump, the pressure is within spec. Have you checked the EGR valve to see if it is plugged or sticking? Have you checked engine compression?
