What is causing the bucking in my Ford F100?

Asked by Sep 14, 2017 at 01:06 PM about the 1979 Ford F-100

Question type: Maintenance & Repair

I have a 1979 Ford F100 Ranger with the inline 6. Everything on the truck
works. The truck starts and runs well with only a few hickups. However,
when I drive it for 15-20 minutes the truck begins to buck like a bronco. The
bucking gets worse the longer I drive it. If I stop and let it sit for a bit the
bucking subsides for a while but comes back when the trucks is driven for
15-20 minutes. I am at a loss as to what the problem might be.

This sounds like the typical Ford Ignition Module trick, I like to replace the distributor pickup at the same time so then you know both units are new.
