My Turn! 06 E350 6.0 missing, rough runing
Hey all, reading up on what to expect, but figured I'd start a thread so i can get answers.
2006 E350 6.0 167,XXX Van
Stock truck, always has been- no Major work done to my knowledge( I saw 38 pages of service history @ ford dealer where I purchased used- showed diligent 6.0 service history and good general care taken, no major issues)
500 miles on oil change(blue rotella)+ archoil
500 miles on fuel filters- some slight indication of possible tank delam, but nothing serious.
I buy fuel @high volume station
started and ran great this morning, 25 minute drive.
parked and sat for about half hour
started up and had slight miss. drove back home,
on highway -stuttering at 1900-2300rpms, get on it and she goes fine, has boost pressures up to high teens anyways. 2 stops in route, got worse and worse running. did not notice any smoke.
by the time i got it into the garage, she barely chugs off the line. missing bad.
I do have a Scangauge, but dont have all the "right" xgauges installed yet to troubleshoot this.
Temp deltas have always been good.
I do have 47.6-48+ volts FMP, and she builds boost.
looks like i need to add a few gauges, I do have the great PDF list and knowledge to install, but what do I need to look for?
Thanks for the help!

Ok, loaded up some more xgauges.
cold start this morning was good, seems like normal. Warmed up a little and started missing.
measured on a "cool" engine
DTC= 1

VLT 12.0 13.6 UP TO 14.1
MAP 14.3 14.4 19.9-20.3

Contribution Test.
Hmmm.
I just got in touch with a friend who works at a medium duty truck shop.
They have a Snap-on and OTC scanners which he said will pull DTC's, and one of em would do a buzz test.
Anyone know if I can do contribution test with one of these scanners?
I will do some more research and see what I can get done with the scanner tomorrow.
Thanks

So you're getting 6 psi of boost at 2500 rpm without a load? As I recall from memory, that's a little high without a load? Then again, this is on a cold engine.
If you get the same results at operating temps, check the following sensors and wiring. Clean if dirty. Use a weed eater wire (or similar) to clean out tubing.
EBP
MAP
IAT2
BAR
Also check the VGT % and report.
Do you still have your EGR valve? Could it be sticking open?
