powerstroke "TOO QUIET" ?????

[henry L.]

i have a 2004 f-350 superduty powerstroke. lately when stopped and idling the normal engine clatter stops and the engine can barely be heard. there is no drop in rpm's and the engine doesnt die. when i touch the gas it comes back to normal. when left alone it is only quiet for about 15 seconds then back to normal. any ideas? is it something i need to have checked out? thanks

WELCOME Henry!
Ya know mine does something along those lines too. It seems when I let out of the gas to coast sometimes (I'll have to try and pin point it a little better) I can't heat the motor at all - RPM's are up, everything seems normal and when I give it gas it acts fine - it just goes "quite". Heck maybe it's normal. Anyone else have this happen?

I've noticed it too.
If I'm going downhill and let off the gas it goes quiet...and as soon as I'm back into the gas it comes right back to life.
This is my first Diesel so I wasn't sure if it was normal or not.....but apparently I'm not the only one who's truck does it, so it must be....either that or we all have broken trucks. )

Ford designed an "engine brake" feature into the 6.0 PSD, I've personally only noticed it in tow/haul mode. the computer basicly kills fuel to the cylinders so that you don't coast so fast.

Also reading into the 6.0 Powerstroke Owners Manual Supplement it mentions somthing about the egine running loud untill it warmed up and the engine noize reduction program starts but that is in the section for adversly cold climates.

I'd be willing to bet that Ford put an engine noise reduction on the newer models. I have a 2000 PSD with a Magnaflow exhaust and it stays loud all the time! (It helps me think! and I have to drive around with my stereo loud -- so everyone thinks I'm a kid who never grew up).

hey, Rodslinger!

RE: your post at my garage (hey, you got a great garage yourself!)

I'm sure someone sells a mod kit to mount the 106mm to the back of your PSD.

Hey thanks cominus! I'm a gun nut so don't temp me, I just might look into it. Can you IMAGINE the looks I'd get in Houston?

Great info as always James, thanks Amigo!

WELCOME to Powerstroke "DirtBag" (that just sounds wrong! ), it's great to have ya. And if our trucks are broke I'd hate to see how awesome they would be fixed!

Rodslinger, you'd be popular! -- everyone would be watching you.

Hey, I forgot to welcome DirtBag -- Welcome DirtBag. This is the place to get answers to your questions, or at least some interesting comments. Got some great people here.

The reason diesels are getting quieter (as I was reading in a truck rag), it might be the automakers are trying to answer the demand for quieter vehicles. You know, they have to appease the California white collar, desk chair types who get a desiel rig to restore their manhood but can't stand the fact that it's louder than their Cadillac!

I remember when I bought my first PSD in 1995. Back then diesels were just barely getting popular. And I remember all the dirty looks I got -- especially from older people (and especially when they saw I was an older people) -- because of all the racket that truck made.

But you know, there ain't no better sound to keep you company while cruising down that long lonesome highway, than the sound of your diesel motor talking back at you.

There must be a mod out there to remove or counter any noise restraint the manufacts install. Probably the same place that sells the mods for mounting the 106 RR!

There is, it's called Banks.

oh and Welcome DIrtBag!!!

P.S. I'm a nerd if you havent figured that out yet. And I think the day that Rodslinger and I square off on who has the most macho/frivolous/outragous toy(s) is beginning to bear down on us all.

I went to Banks and can't find the mod for mounting the 106mm RR!
