No power after cold start
Gentlemen,
My 2000 7.3 has NO power at all after starting first thing in the morning.
It starts fine, and runs fine, but if i don't let it warm up a little, it won't even move.........it like it's tied to a very large tree or something.
Is this normal?
The outside temperature is fairly mild....around freezing or a few degrees below, so nothing really extreme.
Any help will be great. Thanks in advance.

Yes Exhaust Back Pressure Valve sorry.
Usually you can't hear it at the motor just out of the tailpipe but you've probably heard it before to know it's not that. Usually if they are sticking it is described as if you were driving and all of the sudden it's like you flipped a switch and power is restored.
Another thought is transmission fluid levels? Too low could cause flow issues, that go away as it warms.
If you plug it in for a couple hours does it do the same thing?

I have seen some trucks during cold weather that you crank and no throttle change at all when pedal is pressed . Then as it gets warmer, when u press the pedal, it will slowly accellerate and eventually start acting normal. Is that what u are having with your truck?

How long are you letting it warm up? I have to let mine warm up a good 10 to 15 minutes before it really wants to move otherwise it is really sluggish. Plugging it in helps it start easier and warm up quicker, but that doesn't help the transmission fluid when it is freezing outside.
