Did some searching on here last night and got together a whole list of x gauges and there codes to use. Thanks for mentioning that I didn't know. Gonna put those in today.
I had forgotten about the Blue spring upgrade as well. Gonna get that ordered up today as well.
I'll report back with some numbers from the scangauge.

Ok, set up some X gauges
Key on Engine off
FLP= 11.5 -12 Volts
FCM= 47.5 volts
Key on Engine On
All FICM volts within range
ICP= 623 idle 800-950 cruising speed 950-3500 on acceration
IPR= 23% idle 23-65% on acceration
I can know rule out FICM
Next will be the blue spring upgrade

I have a similar problem with my Excursion (along with a much bigger one) but today I just noticed that if I put it in tow/haul mode the "shuttering" goes away. BTW, my Ex only shutters at a steady cruising speed and only after reaching a certain ECT, never during acceleration or deceleration and now never in tow/haul mode. I wonder if the TOW/HAUL turns off the EGR valve?

Let me give you guys an update on my progress. Since I'm a believer that a thread should always be followed thru in case someone in the future searches and finds this they aren't left hanging.
I bought the blue spring upgrade last week (I haven't had a chance to put it in yet tho).
This past weekend I did a bunch of searching on here and believe my problem still lies in the injectors... stiction specific.
Anyways I came across the archoil 9100 and read up on it. After learning more about how important the oil is for them I figured I'd give this a try.
Last night I dumped 16 ozs in and let it idle for 30 min's. A few times I would rev it up.
Today I needed to use it so it was my first ride.
Now I've had the truck for two years and you could NEVER from a dead stop floor it without bogging down. For the first couple of miles it went well, felt better.
It doesn't accelerate like my vette ... but holy cow I didn't know the truck could accelerate like this!... this is like driving a new truck! Even when I was pulling the trailer today it had good power. Very happy with this Archoil 9100 and would recommend it. Even the shutter/bucking is gone for now.
Very much looking forward to putting in the blue spring.
