So Ive done the repairs that ford said was wrong with the truck. This included replacing all the low plugs and wiring harnesses, changing the ICP sensor and pigtails, and cleaning the EGR (however i installed an EGR delete kit instead). So everthing has been taken care of. Why is it, that at 45-55 mph when im at low RPMs, my truck still feels like it misses? It doesnt buck by any means, it just cuts out for and 1/8 of a second and sometimes will do it nonstop. Anyone else had this problem? Fingers crossed its not injectors!
I will say that I have an exhaust leak from the headers to the turbo. That is getting fixed next week but I can imagine that causing the truck to shake pretty violently.
Also, I have been noticing lately that sometimes when I start the truck it will just kinda slowly turn over a little bit then die. Then ill turn the key again and it will fire right up! Whats causing it to not start properly?
Dangit, I always forget to give the specifics. I have a 2003, F350, 6.0, CC, 4 inch lift, 5 inch exhaust, egr delete, sct tune. Today it vibrated a lot at about 1200 RPM id say. and it had a bad start probably 4 times.
Is IPR the same as ICP? I looked at the latest flash that was done and it was back on 9/20/04 flash code 370A-12A650-FTD. I keep hearing about people getting their computers refalshed and it fixing a similar problem. Is this the same flash that I already have?
The IPR is NOT the same as the ICP. On your truck it's right next to the ICP in the back under the turbo. There is a way later flash than what you listed, just be sure that if you have it done you return your truck to stock AND, depending on your SCT model, unlock your SCT to wipe the old VIN locking file out so it doesn't wipe your new stock programming out.

I have the xcallibrator2 SCT tuner. I dont think that there is anyway I can personally change anything on that tuner. I bought it from DJs diesel a few years back. Id like to get a tne with EGR delete on it but I dont think DJs is in business anymore and I dont wanna pay 180 bucks for 3 new tunes that ive already paid for. Will the xcallibrator2 erase any flash updates i put on the truck? if not, i may go try to get it flashed today. I would love it if that fixed the problem!
for those of you who are curious as to the result, turns out that my local ford dealership sucks and didnt even test the injectors! So I had a local diesel shop test them and guess what?!? I have 3 that are pretty bad and misfiring, and all the others and kinda gettin crappy. So Ive spent like 3000 bucks fixing everything ford told me was wrong and now get to spend another 1700 or so to get new injectors! Thats if i buy them off ebay for 150 a piece instead of 250 a piece for the shop. like mcdonalds....im lovin it!
I dont know why there would be a need to replace all 8 glowplus. we never see all 8 bad. the harnesses do get old and break when tring to remove to replace glowplugs. the Icp sensor is a big suspect for that concern. did the tech list the icpv pid? that pid value should be .19-.24 for the most part while in koeo. also was it leaking oil and if so is the connector soaked in oil.
Imo befor we go and say people at the stealership suck understand that as a tech we know the icp issues will look very much like an injector fault and cause injectors to drop and random mosfires to replace an icp sensor can and has cured many of the 03-04.25 injector concerns.
the truck should be reflashed to the latist cal as well befor replaceing your injectors. That is a great cal and has fix a slew of programing issuses. the new cal has updates for the trans, vdf, ac operation and egr as well as injector inductive heating.
the icp has been replaced and when i felt it, it did seem like it had oil on it. I replaced the pigtails as well. No change. i didnt get a read out for the icpv. I was told it cant be flashed now because of the EGR delete.
not having to deal with an customer w/ egr delete befor im not 100% on this statement but I see no reason it cant be reflashed. I think all that would need to happen is
1) reupload your trucks stock prog.
2) reflash with fords softwear
3) relaod your mod prog
the only thing I see that may be an issue and you should be advised of is the fact that if your prog. is not compatable with the latist flash from ford you may end up with a crank -no-start. and will for certin have a mil light on till you relaod your egr delete softwear.
The only way to know is to contact the person/company that is providing the softwear for the egr delete
The reason they said they werent able to flash it was because they were reprograming the way the turbo positioned its veins, with the egr delete there is no was for some sensor to read the egr since its not functioning now. Therefor they could only get through 2 positions of reprogramming then it would lock up or something. make any sense?

none what so ever. the vgt learn is a not part of the program at all. The vgt learn is something you would need to speak your programer about.
If in fact they got to the vgt learn/ test / pid moniter to varify the 2/5 learn then you would have to have the newist programing.
Forgive me but its just a little hard to expain.
The way the update works is simple we upload 3 new programs 1 to each module (pcm,tcm,ficm) then we try to get it learn vgt. the new program is still there and not erased if vgt fails to learn. what would happen at worse case is a slight lack of boost and may be a mil at some point.
I do think based on what I have read is the dealer did not prog the pcm/tcm/ficm. I belive what they are refering to is the egr self test were in fact it would fail test 2.
To me it sounds like the tech just doesnt want to mess with a moded truck. My guess is that he just doesnt want any liability.
you can try to call the shop back and ask for the service manager, make sure you get the acutal manager and not the advisor and explain that you just want the latist calibration installed. explain that you do have a delete kit and you understand that after the recal YOUR TRUCK MAY NOT START
(we used to have an issue with chips going incompatable with new softwear and causing this). I have not seen it happen with a programer as the reflash will wipe it and return it to stock.
If the manager wont help call a diferent shop as the lack of an egr valve is just a b/s deal.
hope this helps.
So if i understand right, once the truck is updated it should theoretically run ok. however, when i put the tuner back on the truck, it may not start then without and egr delete mod on the programmer? I may just go to a different ford dealership. I think the tech im dealing with may not be the sharpest tool in the shed.
