Engine/Transmission (1998.5 - 2002) Losing Power

[tony1461571]

Hi I need some help on this one

A couple of weeks ago when I left work my truck lost power it would move but would not go very fast no matter how much I pushed on the accelerator pedal all I got was a lot of black smoke from the tail pipe. After a short time the power picked back up and the truck ran normal the rest of the way home. A day or so later I was leaving for work in the early morning and it did the same thing again. I had used my exhaust brake to help warm the cab of the truck up before I left and I did this the other time as well. Is there any thing that can malfunction in the exhaust brake that will cause a loss of power? I will say that the power problem did get better when I shut the e-brake off. I have not driven with it on since and the problem has not happened since.



Thanks Tony

Sounds like the exhaust brake is sticking closed when you lose power. Check it for soot build up

Hey! That's just what mine did (does). I got news for you. Either your LP is dead, or your VP is on it's way to a dirt nap. I know mine had great pressure, but it still acted the way you describe. Now, if I rev it a little at idle, she smokes and mis-fires. No power (something I'm not used to), and just wait until you flog it and it stalls. Yup, I think you've been chosen as a 'nuther winner of a failing VP. Just like me.

If you want a place to get a pump at a reasonable price, let me know. Trust me. It's not the brake.
