96 F150 Problem

[Dusty]

My 96 F150 is a 300 6 cyl. and runs rough when you start it hot. It will start fine in winter no problems, but in summer stumbles and dies but will eventually start and run. Only does it after it has been driven, will start fine after it has set at least 30 minutes. Have replaced computer, mass airflow sensor, throttle position sensor, crank position sensor, fuel filter, plugs, cap, rotor, wires, tested injectors, fuel pressure, timing, grounds. Throws ignition diagnostic module code. Run Ok but low power. Overheats, misses, and has a vinigar smell at tail pipe only when running bad. Tested catilatic converters. HELP ME PLEASE!!!!

Welcome Dusty! How old is your ignition module?

What he said ^
Sounds like a Ignition issue.

Sounds like a bad PIP sensor in the distributor.

Ignition module original but tested. Pickup in distributor and coil are new.

What is a PIP sensor? Magnetic pickup and coil are new.
