hehehe... walked right into that one, huh?
If the ICP looks good, something else to check would be the oil temp sensor. I had a 7.3 give me a fit like this one time. The connection was bad the the oil temp sensor and it would surge randomly going down the road. The oil temp would be right and then drop to -40 every now and again. When the temp dropped the engine would surge. Just trying to think outside of the box.

Nope, not problems at all. I appreciate ALL feedback, believe me. I replaced the MAP and EBP sensors about three months ago and have checked the EBP gauge when it was surging... everything seemed within normal ranges.

Hokie post these Values
ICP
ICPV
FICM lp
FICM vp
koeo,low,high at 2500, keep the gauge on these and when it acts up try to get them one at a time .
Did you install the Blue spring, may need to look at fuel pressure, the scan gauge wont read this.

'nother update: It hasn't done now it two days, but I did notice that the ICPV seemed to be a little low at low idle at .75 and 660 ICP.
Once there's ANY gas applied, it's over 1.0 and it's running fine. It still hasn't choked or surged since I first posted this, but I thought it was always supposed to be around or over 1?

I think ICP and ICPV are different was of displaying info from the same sensor. The relationship is like this:
Press Press Sensor
(PSI) (MPA) Voltage
0 0. .02v
200. 1.5 .4v
400 3. 0.73v
600 4 .96v
800 5.5. 1.2v
1000 7. 1.4v

If you using a SGII to monitor you might want to double check codes, particularly th MTH #'s. It could also be related to the tune, some stratigies change reported sensor values to get the desired result.

Take these values like this
koeo(key on engine off) low (idle no AC or radio) high ( 2500 rpm)
ICP
koeo-0 low-625.5 high-1400/1450 operating range=0-4045
ICPV
koeo- 0.2 low-1.0 high-1.8 operating range=0.15-4.7
The cooler weather mite be playing a role it did on mine, once the temps went up so did the Issue. we need to get the values of the test first. then while driving will see what takes place

I'm sure there is a Motorcraft number also but I don't have the crossover for it.

I called our ford dealer here about a cross over Number they said no crossover that this # fits all 6.0 years , there could be a after market # . Hokie you may want to call International the price might be a little lower or even Riff Raff diesel Products.
