1984 F 150
I have a significant loss of power, coupled with what
almost seems like a misfire after it runs for a while.
Starts somewhat slower than it was, but idles fine
till it gets warmed up. As soon as you drive it a few
minutes it idles rough, slows down and will
ultimately stall even if I flutter the accelerator. Took
apart carb and cleaned it, doesn't appear to have
any issue there. Replaced plugs recently but not
wires and ran fine until lately ( at least a couple
thousand miles) timing doesn't seem off, help!
