Just had recall 05E15 done today, didn't really notice a difference with the idle sound (didn't seem any louder). My tuck has always had pretty good throttle response, will test it tomorrow when I get on the highway.
Also had recall 05E15g, 59B01 & 59B01A done, couldn't find any info on what it is. My work order says, "perform recall 05E15, perform recall 05E15g and 59B01a. replace the EP sensor, EP connector and recalibrated the PCM, TCM AND FICM. Part number 4U7A-12A650-BGG filename VXBC7B3. Road tested and check out OK".
Parts used 4C3Z-9J460-A SENSOR ASY AND 5C3Z-12224-A CONNECTOR.
What does this all mean? How many recalls did they do? Recalibrated the what? Does this mean they reflashed my onboard computers? Hope somebody can help. If anything, hope the diesel mileage goes up, getting 14.5 to 14.9 MPG driving mostly highway.
They change the EP sensor and wiring and reflash the PCM. The 59B01 is a "customer assurance roadtest" that gets done when all the recalls are completed, to make sure that there are no driveability problems remaining. You should't notice much noise differnence right away, the quiet idle strategy still runs for 5 minutes.
I really can't tell the difference. I have 3 very talkative daughters so the noise level of a diesel was never an issue to me anyway.
It does seem that the low end throttle response is a little better but, that may be just 'cause I want it to be. Probably isn't really a measurable enhancement from my "oh golly gee whiz" scientific measuring device.
Plus, on my first tank of fuel I have not seen a increase in MPG. Was really hoping for some benefit in that regard. On the second tank now.

I noticed it's relatively 'quiet' (albeit louder than with pilot inj.) until you put it under load . . . going from Park to Drive will instantly get him to bark a bit more. Another thing is the noise difference when it's subfreezing is huge. PIlot still did it's thing when it's cold out but was definitely louder. Let the truck sit out when it gets sub-freezing and holy cow. Definitely louder.
My mileage went up, surprisingly enough. Leads me to believe i was negatively impacted by the very issues that warranted the recalls . . . oh well. He still runs good and I love it.
CanadaGuy, you're saying the quiet idle still works after this recall? Everybody else says its gone!
The old calibration idle strategy had the EGR flowing for 10 minutes at idle... the new calibration has it flowing for only 5 minutes, but I don't know if it's at the same duty-cycle as before. The timer should reset everytime the brake or accelerator is touched. This has been done in attempt to keep the EGR valve from carboning as quickly.
My truck is running much better after the recall. Right after the service it ran like crap and made a loud noise when I let off the throttle. I found they left a wire unplugged from one of the sensors and when I reconnected it the truck ran great. The idle noise is about the same as before which I thought was good compared to my 2000 7.3.
I think I was on page 1 of this post. After having it for a few weeks the truck runs much better sans quiet idle. I noticed that the idle when cold doesn't go up after a few minutes as it did with the quiet idle. I've also noticed it doesn't smell of diesel at cold idle either. Good luck to all...
Interesting. Where did you get your info? First time I've ever heard that. Now I'm thinking maybe my truck is still programmed for pilot injection! It was one of the very first 04 engines put in a truck.
Just got my Blackstone oil report back and have 2% fuel in the oil. Not good!
Maybe I should dump the old program before I hurt something.

I just took mine in and dropped it off last night. I will pick it up on Saturday. I take my truck to a dealer 1.5 hours away and it is a long flat stretch of freeway there, so once I got on the freeway I reset the lie-o-meter and set the cruise to 65mph to see what mileage difference there would be after the new flash, I got an avg of 18.5 mpg on the trip down, and thats with my big 35" mud tires. I know the lie-o-meter isnt that accurate but I only want to see if there is a difference in mpg.
If your engine build date is after 09/29/2003 pilot injection was never programmed into your '04....Prior to that date Ford was still using '03 engine builds. As I recall there were many engine changes from '03 to '04.
Also, for whatever reason, Ford stated that up 5% or 6%? fuel in oil is OK.
Yep, 09/29/2003 is the key date everyone, including Ford, always quotes for the changeover from 03 engines to 04. Or is it just the date the programming was changed? Because here's an interesting fact:
My engine is an 04 (no question) and was built ON that day! Not after! It is marked:
29 Sept 03
It would be really nice to know if it's pilot injection or EGR manipulation so I could make an informed decision about getting reflashed.
As for the 5% to 6%, holy cow! That seems excessive. I was doing a lot of start and stop, in town driving and I figured that was why I had sucha buildup. At least I hope that's all it is.
npccpartsman shared this little tid bit with us a back in August:
If your ICP sensor is on the righthand valve cover it's an 04 motor---That close to end of production date it could be anything--ALL the manufacturer's are like that.
Picked-up mine from the dealer yesterday. Had the recall done and its a little louder but runs real well. No bucking at cold start-up but the turbo pick-up is about the same. I'm happy with it!
My instructor was telling us that when I had my advanced diesel performance course. That's all I have to go on... I've tried to research it on the Ford website, but all it says is that the EGR idle strategy has been changed, but not how or why.
The first production date of the updated 2004 engine was September 29, 2003.
