I'm new to the forum. I have a late 1995 F-150 XLT with the 302 in it. Love the truck! About a year and a half ago it started developing an ignition miss. I have tested every sensor for proper voltage, and all of them are functioning as they should. There is no check engine light on. I have replaced plugs, wires, distributor cap and rotor button, distributor, ignition coil, TPS, fuel filter, all vacuum lines, and many other parts I can't recall off the top of my head. I've run electrical, fuel pressure and vacuum tests, to no avail. The miss only happens at midrange rpms when the engine is under a load; technically when the throttle position sensor is at 2.2 volts, there is a jump in the voltage.

I'm at the end of my experience in figuring this out and wonder if anyone has any experience of this happening and what I need to do in order to fix it.

Thanks!!
