    My 1996 ford f150 xlt 5.8 liter will start and when accelerator pedal is pressed it sometimes will rev the motor and sometimes make the motor pop a few times and the dies out what should I check out

    The EEC-IV has very limited self-tests. Look for these codes:
    241 EEC IV/EDIS module, incorrect self test data
    511 ROM Fault
    512 Keep Alive Memory Fault
    513 EEC IV module reference voltage V

    Other than that, you've have to test each circuit, which is more than I can explain in detail here.

    96 is a obd 2 with the proper tester one can get soup to nuts, 1995 can be tricky some had eec 4 with did not much, unless it had cailf emissions obd 2 like mine was, that drove a jersey dealer crazy

    Your symptoms are almost exactly what mine were on a 92, it was the throttle position sensor. Not saying to change that, just a good thing to test.
