Hello All,
Sorry I have been MIA worked a stretch of 13 hour days pretty much time to get home eat a sandwich go to sleep and do it all over again type of deal.

So my truck is for the most part running much better, once and awhile she still runs a little rough, but not always. I'm wondering if I should go ahead and try and do the blue spring upgrade and change the fuel filters.

I have the scangauge running, FICM voltages look good. I noticed there are x-gauges that do something with each individual fuel injector? Is there any way of diagnosing a bad injector with the scangauge, or is this an entirely different function that I am not grasping?

This blue spring upgrade I understand I can purchase at international dealers, or is it also available through the ford dealer? I'd like to almost run out somewhere around here and buy one if I could rather than have to order it online and wait for it to come. Thanks a million for any input!!

I put one in "just because". It's isn't that expensive nor difficult. I'd just do it! OH! Cheaper at International

 

I also did it and its only a 20 minute job and much cheaper from international do a search and I'm sure you can fin part numbers.

Just bought one last week thru this seller - Ford Powerstroke Diesel 6.0l Fuel Pressure Regulator Blue Spring | eBay

Good price and got here in a couple days.

 

well sounds like its a no brainer to go ahead and do the blue spring upgrade. any other thoughts on diagnosing injectors with the scan gauge? Im just curious if theres maybe one or two injectors that are messing up once and a while
Thanks again !

The SGII won't do anything with diagnosing injectors. I don't know of anyone who has been able to get those codes to work at all. You really need something like auto enginuity, at a minimum, to do any meaningful injector diagnostics.
