I have been gifted a p0269. Symptoms are slight haze at idle, I wouldn't call it a rough idle but it's not smooth, pretty much a cylinder miss, the more fuel applied the more smoke exhausted, power loss but not even noticeable.
I didn't realize i had a problem until I got off the interstate after a hour and fifteen minute run. I noticed black smoke pulling out from a stop light. My wife who was following me, informed me that it was smoking the whole trip. Note it wasn't enough smoke for me to notice it in the side view mirror while driving.
So far I've tried to clear the code. It comes back of course. I listened to the compression using the starter wire and it sounds perfectly fine. I unplugged the vacuum pump and listened to the injector clatter on start up, nice even sound. I checked for blow by from the oil filler neck, it looks fine too.
Run cylinder contribution test. Easy to see if there is an injector issue. Also you can switch off each injector to check if the behavior changes.
Hello Hartwig. I bought an Ford IDS clone several years ago. Had a hard time trying to get the system running and once I did, I was afraid I could or the system would change configurations on the truck to the point that I'd never figure it out. So I put up and haven't touched it since. I don't feel comfortable using the system.
Could I simply unplug the troubled injector, start the truck and see if there is a noticeable change.
Injector replaced. No more codes as of now. No miss fire or black smoke. Have an extended crank at the moment. VGT was at 85% because I forgot to connect the map sensor hose.
I wonder why an injector would fail within 25k miles. Injector buzz always sounds perfect. Ficm have never been below 46.5v, FLP 13.5, and FVP 14. Fuel pressure has never seen below 55 psi. Hpop around 600 to 700 at idle, over 3k wot. I do oil changes at 10k and the lab says it would be fine to run more than that. I use T6. I drive 1.5 miles to work and back everyday. Weekly 1.25 hr drive at interstate speeds. Fuel filters were done last oil change. I do 2oz of hot shots diesel treatment with about 75% of my refuels. Zero oil additives.
Not that I am saying that your issue(s) is due to your extended OCI, but I am curious as to the oil you use?
I have done a few 7500 mile OCI's w/ a quality 5W40, but 10k is really "bold" IMO. With HEUI injectors, I do not pay attention to those lab recommendations.
I just received my oil analyses at 250k miles. Posted the results over on the Org. Changed it out at a bit under 5k miles, but at (apprx) a year interval.
I'd like to see a UOA at 10k interval. Metals and viscosity! Would you mind posting a few?
Where were the injectors purchased 25k miles ago? New or remanned?
Hope not. It could have been just that one injector. Unless new spool valves are installed, the remans seem to have more of an issue with occasional ones that just don't seem to last.
Personally, I would drop the OCI and see what happens. I suppose you could throw in some Archoil also .... just because. I did that on a couple of oil changes just to see what the UOA would look like.
Thanks for the UOA attachment. You aren't driving it much (neither am I).
Shell rotella T6 5-40. I can't say the exact mileage on the injectors but a safe bet is around 25k and they are oem remans from Thoroughbred.
I'm with you on the oci bismic. That could be my source and a complete set of injectors may be in my future.
Clearly viscosity continued to drop with the extra miles (as expected) but it looks like the rate had slowed down considerably.
SAE 30 weight viscosity range - 56.5 to 68 SUS OR 9.3 to 12.49 cStokes
Your viscosity had dropped into the middle of the 30 wt. bracket, but with quite a few 5k mile OCI's, I had dropped to the 65.5 SUS (very high 11's for cSt). I had wondered about that trend (viscosity vs. miles) every-so-often. I am not a "run 30 wt oil" fan, but this is good information for me, and the metals look very nice. The add pack looks interesting (Ca and Mg and P). When I ran T6 as a trial a few times, I saw less Ca, but a lot more Mg. in its place. I suspect a bit of cost "optimization". Good to see the P. (anti-wear) still over 1000, but maybe it is down a bit. That slowly depletes with miles driven, and I think 1000 ppm is an important minimum. Again - thanks.

You're welcome bismic. The first year had archoil added and took several oil changes to remove it. I switch to the T6 from T5 when I stopped using the additive.
The truck is running fine again. After about a 5 mile run, the extended cranking time is gone.
