I just recently bought a 97 F350 7.3l to pull my mud truck around on weekends. I had a buddy scan the truck for codes and I got the famous cam sensor....which I replaced yesterday. Truck idles a lot better and doesnt stall now. The problem im having is when going down the road sometimes there will be a power loss and loud hissing up front. I read on some posts that the EBPV causes this. But if I let off the throttle completely and let it coast for a second or two then get back on it, the truck will take off until this happens again


Is this what I am expieriencing??? I unplugged the EBPV from under the turbo and still had the same issue. Can I unplug it and use a wire or something to keep it pulled open??? The truck is not throwing any codes for this, and i checked the MAP sensor and the lines were not clogged. Any help regarding this will be greatly appreciated! I will need to tow with the truck this weekend so hopefully it is a simple fix.

 

Please if anyone has had this issue or could give me some tips on what else to check i would really appreciate it......

I unplugged the ebpr under the turbo and seemed to run a little better when starting to warm up, but i will no for sure or not on my drive home from work and can post an update

 

Yes you can use a wire to keep it pulled open.

BTW welcome to the forum.

 

Thank you for the help....I should be getting the exhaust chopped off today to help it breathe some more too!!

I will post an update after I see if unplugging it helped until i can get the wire to hold it open
