Is this normal??

It just did it this morning (it was 35 degrees this morning for the first time,has been in the 40s and 50s). I cranked the truck to let it warm up like always (about 15 mins while I get finished getting my son ready for school) and I thought the exhaust sounded a little louder than normal for and idle. As I left you could hear the turbo loud out the exhaust and as you slowly gave the truck more fuel it seemed lacking in power. Then it would all of a sudden kind of jerk as the turbo kicked in(boost gage would jump to about 5 psi). I played with it a couple times and it did it every time. You could go ahead and mash the motor and it kicked in fine and ran fine. It was only when you were easing on it. Any way I got to my sons school and as I took him in the truck idled for another 5 to 8 mins and when I came back out it was back to normal. Idle or taking off it was totaly back to her good old self. Its never done this before including last winter in all the snow etc...

It's normal...

Its the EBPV (exhause back pressure valve). It activates when ambient temp is below 40F and oil temperature is below a certain temperature (not sure how cold). It helps the truck warm up faster.

You can read all about cold operation of the 7.3HERE

Tkanks guys! I feel better now. So if it was to do it all the time while driving down the road I guess that it would mean that sensor (EBPV) is bad? I had a 97 OBS that started doing that right before I traded it off. I always wondered what had caused it.

That, or sometimes the tube will get plugged up. I've also heard of the tubes rotting away. I haven't done this, but if you unplug the EBPV solinoid it won't ever activate.

I kind of like the way it sounds... haha.

Gut the EBPV? What will that do or not do? Just make it take longer to warm up?

It flows much better and the truck warms up just as fast. Even at idle.

It wont hurt your warm up time honestly.. if you want better just get a chip with a high idle.. it lets the truck breathe way better and as i've said a million times the exhaust sounds way nicer with a straight pipe.
