177k, just got month ago. Vegan major tune with cap, rotor, pill change, pvc.
Haven't got to wires and plugs yet, but wire set looks pretty dated and fragile. Fuel filter not in yet, have new shocks to install.
Since shortly after cap and rotor, starts began with periodic slow turn like timing, then start, with initial high idle, leveling out until warmed up. Progressed within days to start, warm and die with no immediate start. Went thru vacuum connections, tightened air box, ect,
Now initial start up running smooth, then sound rough and levels out smooth and back to rough then no start after shut off. Let sit starts hard.
Any knowledge and direction would be greatly appreciated. Reading endlessly on haynes manual both down loaded and book.

Hey could i get some more detail the truck. Like did you just buy it and did it run when you got it. Or you know just a quick summary of what happened or what you have done to it.

Yo Jeff,
Welcome!
Try a Self Test for Diagnostic Trouble Codes by my pal, BroncoJoe19 @ Code Reader.....

PCM stores the Self-Test program in permanent memory. When activated, Self-Test checks the EEC system by testing memory integrity and processing capability, and verifies that various sensors and actuators are connected and operating properly.

Do KOEO test First. Post Code(s) here according to KOEO and KOER.

A helper can assist you by counting the codes. Some use their smart phones to record them.

BEWARE OF FAN, BELTS, PULLEYS, HOT HOSES, IGNITION HIGH TENSION WIRES, AND ENGINE COMPONENTS⚠

Or ask local mom and dad parts stores if they will test it for you.

Or purchase a coder reader such as Equus 3145 Innova OBD I Code Reader for Ford EEC IV Engines at Walmart & most parts stores.
