Waste Gate Problem?

[sds329297powerstroke]

I have a 1997 Ford F-250, It is stock other than I hacked the muffler for a better sound. On cold starts my turbo hisses and I have no horsepower. If I lay into it there is a thud and then the turbo whistles again. but as soon as I let off when I get to speed, it hisses again. The only time it goes away is when I get the truck fully warm and then let it sit for 10-15 minutes. on days above 40 degrees it does not happen. I need it fixed right away because it is killing my fuel mileage. Please help!!

Sounds like your EBPV is acting up. I dont know the fix but I do know there are people on here that can tell ya how to fix it!

i dont know what an EBPV is. is it an expensive fix?

well on a 99 there is a steel tube that comes up the front of the motor from the left exhaust manifold. There is a sensor on top of the tube that will plug up with soot. You can take it off and clean it out and clean out the tube too, you can blow back through the tube with air to make sure it is clear. Hopefully yours is the same way. That sensor is the exhaust backpressure sensor.It controls the warm up valve.

im pretty sure you can just unplug the EBPV. Im going to do this to mine this weekend. i hate that crap. i dont care how much it helps warm it up.

I have never had mine kick on since I have owned my truck and it has gotten pretty darn cold. I wonder if min is already unhooked. I havent checked!
