Start with the basics - an engine misfire under load (low RPM and slightly increased load in a high gear, such as starting to climb a grade...) can be from something as simple as spark plugs or secondary ignition (wires/coils/etc). Start there and think simply first. If you verify all that is good, then you will need some test equipment to see what is happening when the concern occurs. Good luck.

Yes. When I mean secondary ignition, though, I mean wires, cap, rotor. Double check the wires and make sure they are routed correctly and not crossed. Also verify good quality parts and fitment. Finally, it's not unheard of to have a bad spark plug causing an intermittent misfire. Or one that got accidentally cracked installing it. Stinks to double your work, but removing the plugs and inspecting again is not a bad idea either.
