Unhappy Trouble Codes? Insight Finds Them, SCT Does Not


Watch the video please, it explains most of my issue. I apologize for the long video, dirty truck, and southern accent in advance. And my Insight is temporarily mounted with the suction cup mount, so excuse that as well.

And could someone help me figure out how to determine if I have a miss? I understand what it is, just a misfire of the injector, mostly caused by a sticky spool valve, but for some reason I cannot pick out what a miss sounds like.

I am running T6 5W-40 Synthetic, and my fuel pressure is holding at 65 PSI (at least it was until my isolator busted wide open :doh).

Thanks man, the truck is disgusting right now and I still have yet to find some time to put on the '05 conversion, along with a long list of arts sitting in my garage. Hopefully next week I can start on some of it. But it sounds good to me as well.

I'm gonna order some Rev-X, along with an oil bypass, new isolator for the fuel pressure gauge, and get a bunch of Ford cetane booster and see if I can't make her run better than ever. I've had way too much trouble with injectors, maybe I can make 'em reliable after this round of mods.

For a contribution balance fault, the computer "makes up" the difference by changing the timing of injection...you'd not likely hear any change with only one injector failing/failed. I had TWO injectors to fail electrically and the only indicator outside of the trouble codes was a significant hesitation at throttle demand. The AutoEnginuity diagnostic tool will graphically show you a non-contributing injector as will the Ford WDS or Rotunda tool. Neither the SCT nor the Edge have the capability of diagnostics tests. It is likely worthwhile to take the truck to a service center, borrow an AE - or spring the $$$ for one, to get the complete report from your truck's computer on this particular contribution balance fault code. An injector "buzz" test will show the problem if one exists. And yes, Rev-X or Hot Shot's Secret is a good oil additive to address sticktion that may be the cause of an injector balance fault - both are less expensive than a new injector BUT a broken injector is a broken injector...these additives don't fix something broken, they only clean up an otherwise false-positive indication with the same characteristics.

Good luck!

Jonathan

So you're saying if that code is present, it is too far gone? Or do I need an AE to really know for sure?

Should I throw some Rev-X in her real quick and see if it fixes the code?

Well it looks good to me now, i'm running the Amsoil by-pass and i think anything you can do to help the injectors is a plus and i also run Ford cetane boost in the fuel all the time i get it in the gallon cans 2 gallons cost less $$ than a case. I also keep mine on a Battery Tender Plus because mine sets a lot but try and take it out once a week and run it hard to keep the turbo and egr valve working

I agree! Where do you get a gallon of the Ford cetane? Do they have it in stock, or is it special order?

I would run the oil additive first before replacing an injector.

The AE/WDS can perform a test of the injector itself BUT the code may be thrown because it is stuck just as likely that it is broken (mechanically in the coil, electrically in the contact, etc.). The buzz test may identify more than one injector having an issue...you can have one out of tolerance and others nearing the threshold but still within their operational range.

Run the additive first. The code might go away BUT I wouldn't wait even several hundred miles - use an AE or WDS as it would be worth it to identify a failed injector earlier rather than later. If it is failed then the extra work placed upon the other injectors may cause them to fail prematurely too.
