NEED HELP

I am experiencing a problem w/my 2003 6.0 super duty. While driving on a level road and maintaining a constant speed, the truck surges slightly as if the driver is pressing and releasing the throttle pedal. I have a boost gauge installed and the boost surges approx. 2 psi. You can hear the turbo whine up and down in concert w/ the boost gauge increase and decrease. It appears the truck in being told to accellerate and decellerate. Ther is no surge when the truck is goung up a grade or under a load. It occurs only while driving on a level road while maintaining a steady speed. Makes no difference w/ cruise on or off. The code that pops is a p2263 Turbo Charger System Performance. Any ideas what may be causing the surge?

 

I have an early 04 f250 doing the same thing. It does not do it everytime I take off, but I would say 2 out of ten times. It feels like either the turbo is kicking up or the fuel injection is flicking on and off. It's a bucking feeling. I've had the in the truck in the shop going on for the 3rd time to get this fixed. Can anyone out there tell me what's going on. Then, maybe I can tell ford how to fix it finally. Go figure!

Oh, by the way, I got my idle problems fixed. woo hoo. I will give Payton Wright Ford some kudos, they are at least willing to work on it. Changing dealerships was some what helpful. Thanks forum.

 

This info is from the Ford website in reference to code P2263

Mine used to buck at 70mph or so, cruise on, going up a light hill. Disconnect of my EGR and a new EBV solved it.

 

I have just had this code come up as well. Here is some info I found on another forum on it:

DTC P2263

Condition Description :: Turbo/Super Charger System Performance

Fault Trigger/Comments :: - None -

Probable Causes :: MAP hose, MAP sensor, CAC system leaks, Intake leaks, EP sensor, exhaust restriction, exhaust leaks



For me though, I am 99% sure it is because I have an exhaust brake that I just finished installing and trying out...

 

Does your truck surge when the cruise control (if you have it) engaged?

I find that some road surfaces have a subtle bit of ridging in them and combined with your foot on a sensitive fly by wire pedal you can get a slight harmonic type of ride and you with out really noticing it rock on the pedal ever so slightly giving a slight jerky feel.

It may be nothing more than your foot beating time to the road???

 

Ah sorry forget my post above I missed the part in your post about the code.
