I have a 1996 ford truck with the straight 6. It skips like it's missing when going up hills. I believe it might be fuel or spark related

Something is weak in the ignition…

Replace the coil, plugs and wires.

Sounds spark related to me, consider checking &/or replacing the plugs & plug wires.

My 1994 Ford truck started to do the same thing, felt like skipping or missing but no check engine light. I inspected the spark plug wires and found corrosion on one of the wires where it plugs into the distributor. Replacing the distributor cap and spark plug wires fixed the problem for me.
