Odd acceleration problem

my '86 F150, EFI 302, manual transmission. Say your going down the road at 50-55 mph (other speeds too, just an example). So your cruising along and you want to accelerate to 55-60. No need to downshift, just lightly press on the gas. Well you do that, and nothing really happens. There's no smooth acceleration. After a certain point you kinda feel it kick and go, but I don't want it to kick and go, I want it to smoothly accelerate. This is without downshifting.

It really pisses me off, and I'm not about to take it to a garage so they can spend days and dollars replacing everything just because it's an old truck and they don't know what's wrong with it either.

I had a 88 Mustang that had the same problem. I replaced the clutch and all it's goodies (plate, bearing, etc) and was good as new....only cost about 140 bucks and a weekend in the drive way. Can you make it slip when you rev on the gas?

Im sure other people will chime in with a better soultion then mine. Good luck.

I really like that thinking, but I don't think the clutch is slipping. It doesn't even seem to rev up at all until you give it that little extra gas.

Tps?

Have you tried pulling codes from the computer? Sounds like it might be a bad or out-of-adjustment Throttle Position Sensor(TPS).

I'm going to vote TPS too. Check the manual for how to ohm one out, but you will need an analog multi-meter to do it. It might have a dead spot.
