Warm up valve

[J350superduty]

I think my warm up valve is sticking on a 99 7.3 Is this a common problem? Where is it located?

It's called the exhaust back pressure valve (EBPV) and it is on the turbo pedestal - exhaust side - at the base in the back. Lots of fun to get to. Do you hear a vacuum cleaner sound from your exhaust?

Here's a picture I found:

Yes that's exactly what is sounds like, and when I push the accelerator to the floor it will stop the suction sound. Thanks for the pic that's extremely helpful.

if its not cold where you are you should delete it. more flow lower egts.

is there an artical on deleting the valve?

You can buy the housing with the valve removed and the holes welded shut, or you could pull it yourself and just cut the flapper off. Or, you can gut the pedestal and just wire the valve into the open position. Here's a video of the gutting of a pedestal:

Are you supposed to hear that sound at all while it's warming up? I hear it until my truck warms up to about normal operation temp? Is this normal? I'm just trying to track down why my truck sputters and nearly stalls (sometimes does) until it reaches the low operational temp (usually about 10-12 minutes). Not trying to get off topic either - just didn't want to start a different thread yet if I could find the information I needed in different places. Thanks.

The sound is normal, but the spitting and sputtering isn't.

I have the ebpv delete pedestal but my truck will still go to high idle when I start when cold sometimes. Will it still got to high idle mode even if the ebpv is deleted?
