HISSING SOUND??

Hey, my 2000 f250 7.3 is makin a hissing sound at about 30-40 mph. Its not when i hit the gas pedal, its when im going that speed (30-40) and let off the pedal just a tiny tiny bit. It will make the same sound around 15-20 mph but not as much.

N its weird i kinda feel a slight vibration on the pedal when i hear the sound, maybe thats just me. The sound is like when you stick your nail in a tire nozzle and let some air out.

I have 230k on it.

No boost gauge, dont know if im leaking turbo.

Anyone know what the hissing could be??

Could be the EBPV shutting. Try unplugging it and see if the sound goes away. Do you notice any loss in power when it does this? BTW, your throttle is electric so any vibration you feel is just the cab.

Definitely sounds like your EBPV, its perfectly normal to do that in colder weather.
you can unplug it or hook it up to a switch to be used as a type of exhaust brake.

unplug it with the engine off and it will never close again so you will never hear the sound again. It will not set the SES light and everything will be back to normal.

as for cleaning it.... my vote it GUT IT!

look up "EBPV delete mod"
its a little time consuming but you will never hear that hissing sound again and you will have the peace of mind knowing that trash is not in there anymore.
