6.0L Hesitation
Hey there, I have a 03 6.0L P.S. I am begining to think this stands for something other than Power Stroke if you know what I mean. I have had the typical problem with the turbo wastegate hose blowing off. The dealer finally replaced it after being in several times. My problem now is that I have a hesitation. Here is the history. The truck coughed and sputtered blew black and bucked like, well you know. This happened under excelleration at about 80 to 100Km/h. The problem is some what speratic. The only thing the dealer could find was a low fuel preasure reading. After a bit of a fight I had a new fuel pump. Yea ha problem fixed. NOT it has continued but only happens every couple of thousand k. There have been no turbo codes so they wont replace the turbo. Should I insist that they replace the EGR valve. From what I have read this could be it. Does anyone have a better idea.

Sorry about the incorect wording. If I was a Diesel tech I wouldn't be here now would I. After checking the report from the Dealer the part in question is CAC tube. As it was explained to me it takes the excess air that the turbo is making but the engine is not using and recircleates it through the cooling systeem. Is this wrong.

sounds pretty wrong. the cac is the charge air cooler i believe, in other words, the intercooler.
there is no reason to run boost into the cooling system. i think you might have misunderstood, but maybe it is part of the ebpv ... i think we're getting closer to figuring it out though

Sounds like your turbo veins are sticking and you've been experiencing an overboost for a while. That's what causes your hoses to blow off continually. You may or may not have a code from sticking veins on an 03. If all they're looking for is codes in the computer then they are incompetent to start with. It's not ALL in the computer--some is in the tech's head and sounds like yours doesn't have one. Tell them to clean your turbo and I bet your problem will be solved. Also, if you don't have the latest flash then ask for it as it will "exercise" the turbo veins to help keep them from sticking.

Thanks for the input. I was feeling a little ridiculed for a while. I do believe it is part of the intercooler. That would make sense. That seems to have been fixed. However the hesitation has occured since. Someone mentioned that it could be a faulty EGR Valve (exhaust gas ?) however that has been replaced when they did the fuel pump. Is it faulty, who knows. The same guy mentioned a sticky turbo however there have been no turbo codes. The codes on record are PO-132B and PO-0402 I have no ideas what they are.

Here is a code explanation from the Ford Technician guide:
Sticking or stuck turbocharger
This would be caught by a P132B, P0299, or P2262, all turbocharger issues must be
verified with a KA test prior to turbocharger change.
If you had a P132B it directly means a sticking turbo charger and sounds like your tech either didn't know what it was or was too lazy to clean it.
p0402 is a sticking or stuck EGR valve

You might also want to try a different dealer -- ask around and see where people in your area take their powerstrokes to. There can be a vast difference in the techs at the various dealerships, there certainly is in my area.
Good luck...
