My truck has had an intermitent "knock" at idle for awhile. I finally got around to scanning it. I have the AE ScanTool with the total Ford bundle.
I ran two injector buzz tests and both came back clean.
I then ran a cylinder contribution test and it came back with two codes:
P0269 Cylinder 3 circuit contribution/balance fault
P0284 Cylinder 8 circuit contribution/balance fault

Other than the rare knock at idle it seems to run fine.

Any ideas?
Thanks,
Adrian

Thanks, I'll give it a shot!
Can I just buy the blue one from international? There is an international shop here in town.

Has anyone here installed the blue CPS? I've been researching and from what I have found the black one was made as an upgrade to the blue one.

The blue one is actually for the DT466 engine. It works in a 7.3 but it also retards the timing

:agree:

I wouldnt run the blue one unless it was my only option. It will retard the timing about 4*

Unless you tell your tuner you are running this so they can correct the matter I wouldn't do it.

So it sounds like my best option is to find a black one?

Been wondering about this myself.....had similar code on Cyl Contribution Test, exept #8 only.

I think this is where you tell me that the International part # 1821720C99 for a black one is no longer available (on Guzzles site where he mentions the gray CPS problem).

Guzzle's CPS R&R page with Info about Gray CPS Issues
