Miles? History of the problem? When do you notice it (constant or intermittent), etc

Re: 94 powerstroke loss of power

Clarify "loss of power". Does it stall? Or does it just fail to provide the usual amount of horsepower? Does this happen while going down the road?

Automatic or manual transmission?

Re: 94 powerstroke loss of power

When this happens, have you tried pulling over and seeing if the engine responds to the accelerator while standing still? (Before restarting the engine, that is.)

Re: 94 powerstroke loss of power

But it does respond to some extent. Well, that eliminates one possibility I had, that it was the pedal, either the position sensor or the idle switch.
