94 powerstroke

[Mel0520]

I have a 94 powerstroke 5 speed when you drive it. It will act like you let off the gas you pump the gas pedal a few times it will blow out smoke and go again any ideals

Just asking, I'm not challenging you, are you sure that it is a PowerStroke? In '94 there where 3 diesel options (IDI, IDI w/turbo, and the PowerStroke). When does it do this? Just off idle, cruising, accelerating, merging? All the time?

[Mel0520]

I was told it is a power stroke because it does not have a throttle cable. It does it when you drive down the road you have to pull over and pump the throttle then it will rev up then you can drive again it does this to much to drive on the road

Does it do it more in a certain pedal spot than others? Thinking the tps is getting a dead spot in it

^^ that's kinda what I was thinking as well.

And in '94, didn't they offer a directed-injected turbo motor, just not yet labeled as a powerstroke?

Someone told me it might be a pump control module

Ok, PowerStroke. When it does this does it cut straight to what seems like Idle or does it struggle to keep going?

That's gonna be hard to determine. With a manual, the momentum of the truck going down the road is gonna keep the revs up. The OP would have to put the clutch in and work the go-pedal; if it acts up then, it suggests a pedal problem; if not the position sensor, perhaps the idle switch is not holding closed.

It goes to a idle you have to clutch and pump the gas pedal 10 to 20 times before it rev up
