no power
 

94 b3000 has very little power at low rpms, it takes about 50 feet before the truck starts to gain power, then its fine until i shift to the next gear then no power for another 50 feet, the rpms dont come up even with the truck floored until the truck starts moving a little faster. once the power kicks in she climbs hills easily. new fuel pump, filter, maf sensor, someone told me its compression? if its compression wouldnt i have no power all the time? cat is clear no blocks, thanks guys...

Is that the Ford Vulcan engine?
Does it misfire? How old are the spark plugs, coil pack and wires?
Are there any vacuum leaks?
Is the throttle position sensor working alright?

no power
 

um new plugs, wires, cap. tps not sure, no code came up for it but i will check it tomorrow, ive found a few broken vacuum lines and repaired what i found, vulcan motor? to be honest im not sure, its the stock motor on the 94 b3000. thanks for the help, ill check the tps in the morning.

oh and also a small miss, the engine is very slow to rev up even in neutral in the garage.

You say new cap. That means you have a distributor?
You have new rotor also?
How about replacing the coil?

If you have timing advance weights in the distributor, check to see if they are sticking and if their springs and posts are in good shape.
