Hi new it this forum, here's the stats
1999 Ford E450 7.3 Powerstroke Turbo Diesel 16' cube van

The issue I'm having is lack of power. I can hear the turbo working and yet I'm lacking alot of power. It kinda sound like air escaping, I'm thinking the waste gate might be stuck

As well when I leave the truck idling, it will always overrev untill I apply the brake or press on the gas. after about ten second it will start to rev again.

appreciate the help in solving this!!!!
Hate spending my hard earned money at a garage!

 

When you say cube van, do you mean a truck chassis with a cube box, or a Van chassis with a cube box.

 

check your
turbo boots
ebpv

 

Nothing wrong, thats normal, Its going to do that when its cooler out! Helps it warm up faster...

 

Not if its a Van front end. Van turbos DONT have a wastegate, or an EBPV.nor do they have intercoolers, and the plenum from turbo to engine is solid and made in an A configuration with no boots.

 

Almost sounds like the truck with the EBV but if it is a van based unit, that isn't going to happen. The tune for high idle will default back to idle when the brake is pressed though, just like any vehicle in the warmup program.

If you have a lack of power you have either a boost leak or an exhaust leak. Exhaust is easier to find because it can be seen where soot deposits. The intake side requires a boost leak detector or if lucky a quick visual inspection may turn something up.

Oh, last but not least, and less likely, is a fuel issue such as clogged filter or weak pump.

 

Sorry, Didn't Think Again before I typed....

 

I worked on an 99 or 2000(I cant remember) E-450 cube box van last summer that had the EBPV on it. Double check i bet it is on yours. TO check, you can pull off your dog house and look under the turbo and you will see a metal rod coming off the turbo pedestal and stretching out and attaching to the bottom of the turbo, exhuast side. While you are in there you can inspect the up-pipes and the center section of the turbo for exhusat leaks. They will appear really sooty if you have one or some.

After you confirm you have the EBPV, you can go about cleaning or replacing the EBPV tube that comes off the passenger side manifold and the EBPV sensor that resides in front of the HPOP (tube connects to it) to cure some of your no power problems.
