studder/surging

I need some help guys, I have a 2006 f250 6.0 and it started surging in a way when I start driving it in the mornings, and will do it till it warms up to about 120... that being said I let it warm up till 90+....... just wounding if I could get pointed in the right direction on what it could possibly be causing it and how to check it if possible. thanks in advance

Do you have any way to get some readings from the truck? ICP/IPR/VGT/Ficm/fuel pressure?

Just shooting from the hip it could be stiction/bad fuel filters/bad ICP/IPR/Fuel pressure/wrong oil/wrong oil filter/vgt sticking and much more....

Using Torque, you will need to add the Ford specific PID's to get all the information for these trucks
you will see the addon in the options

In my defense, I was unsupervised

General note:
For all those wanting a premium silicone sealer Kubota 70000-73764 is the best your gonna find. This is a hybrid gray silicone that uses solvent rather than acid to start the curing reaction, this makes it safe for aluminum and and any surface that involves coolant.

While you are waiting to set up the scan tool, you might try disconnecting the ICP sensor and see if that helps any.

k I'm starting to lose hope with this haha... so last 6 months has entailed a new ipr valve, vgt valve, and I just replaced the icp and ebp sensors today with a fresh oil change, the exhaust back pressure circuit code went away.... now the only code I get is a obdII code.... so I cant for the life of me figure out why it's still got a studded when goin down the raod... I'm running t6 rotella just like I always have and buying all motorcraft filters like always... any help would be much appreciated... another things I checked was my ficm which stays right at 48.4 volts plus or minus .2 V....... I did have someone say it could be my egr valve is that possible? and my truck is stock except 4 in exhaust and a edge programmer that was in it when I bought it.....thank in advance for any help
