same sluggish 6.0 here

i have the exact same cold start-up problems. if you don't let it warm up for 10-15 mins. it will barely move on flat grade. when mine starts up it sounds so loud and will not idle up like it used to. the sound is like a knocking sound. when it runs for a while it runs just fine; poiwer idle acceleration engine sound. its like a doctor jeckle/ mr.hyde truck. it an 04 SD 6.0L diesel 4x4 4 dr. lwb duelly. i pull a 32' rv all across the country in all conditions and that motor or truck has never failed . it has ran for days an pulled tons endlessly. it was made to work. i have keep clean fuyel in it and changed oil and filters religiously. i guess they all have to have a little something go wrong. i read about these egr problems. i wonder if that could be problem. i also took and changed the flex fit rubbers on the cold air induction and found black oil(not much) but a trace in the pipe coming from turbo. What is that? That can't be normal. i'm having problems with dealers. evey one i go to doesn't fix problem or they say its not covered under warranty. i have 60k miles and it shouldn't run as horrible asit does now. ANY HELP PLEASE. Im near palm springs, ca

thanks,blt2spd, i wish there was a clear cut ,cheap remedy.ttyl

 

take it to the dealer and see if it has been updated with the new flash ......mine did the same till i took it in and they re flashed it with the new stuff and its great now

 

thanks jeff,do you remember what that cost ?

 

i think its around a hundred bucks to get it reflashed

 

i have that issue sometimes too. it makes a loud sucing sound when i do get it going then it will kick in and take off. i think mine is sticking turbo vanes when it is warm the issue is not there and the turbomakes wierd sounds during this cold time.

 

mine was weak as hell when cold when i bought it. the dealer found 2 bad injectors in it. changed them and it ran like hell for ayear now it's doing it again. also has egr and oil cooler leaking

 

Mine was doing this as well, i took my truck to the local dealer to get the oil changed and they reflashed my computer for me as well and it runs perfect now, it used to take about 15 mins idle to warm up and then it would go, now i can start it and let it warm up for about 2-3 mins just to let everything moving and then i can take off. The computer reflash was $65.

 

Hey guys mine was doing the same thing as well. I had the smoking/sluggish problem up hills and this problem and the dealership cleaned the EGR(for the smoking/sluggish problem) and replaced some injectors(for the cold start problem). I was in California at the time and it wasn't even that cold. It never really got better, but the sluggish/smoke problem was fixed. HOWEVER we talked to a corporate lady who read us all the recalls we had on ours. One of the recalls was "reclaibration of the control module" issued in 2006 which had never been corrected on ours. The page she read with the symptoms matched a lot of the issues we were having with ours including this one. Maybe check into that?
Ours is 2003 F350 6.0L btw.

 

Gotta love them 6.0's

Could be your glow plug control module, or your enjector control module
or both

 

there is a "bulletin' out on fuel pump systems . Under warrantee!

 

Thanks to everyone that responded,I'm going to take it to the dealer and have it fe-flashed,that seems to be the cheapest way to start .Then if that doesn't fix it i'll go from there.:icon_ford:

 

Slow Acceleration

My acceleration with Cold Motor was beoming worse so I had the Oil changed at the dealer,,$99 Deal plus 5% rebate on Ford Card,,,Now my High Idle during warmup is not working idles at 750 RPM and never goes to high idles of course it's 75 at 8:30 am here in Albuquerque & Now it's a real dog will not hardly take any fuel until it's fully warmed up! Do you suppose it dropped the flash program?

 

another thing that you might try doing is using the Lucas oil power treatment. You use half a bottle every time you fill up your truck with diesel. The diesel mechanic told me to use this because it is supposed to somehow clean out your trucks system. Give it a try. I gained about 5mpg's and about 10-15 horse.

 

Mine would do the exact same thing about two years ago. It would crank, no start, no oil pressure, etc. Then it would finally crank over and just sound and feel as if she was going to shake apart.

Ended up taking it to the dealer and getting some injectors replaced along with the HPOP, Fuel Pump, and having both the FICM and Computer reflashed.
