What is causing the bucking in my Ford F100?
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.
