Soon as we get internet ill get the logs over to you. They are on the same day with the same driving style on the same route. His truck is the same as mine to a T. Only difference is color. Exact build dates im not 100% on but i think they are within 3 months of each other. I dont have my exact letter i got in the mail for the recall, but this is all it said so im not sure of TCU updates. Would forscan tell me the revision?TopherSho said:

Did the dealer change your transmission fluid? Or add fluid .. and were you rubbing non-oem fluid prior to the 'service' ? --> just thinking outside the box of ''what if'' they mixed fluid types if you have non-oem tranny fluid, or the tranny fluid is too low or too high.
Negative on a fluid change. Fluid thats in it is the same thats been in it from day one. Truck was only at the dealership for 20 minutes if that for the reprogramming. When the surging first began from the condensation i checked my tranny fluid and its right where it needs to be. Nor did it look dirty or smell burnt.TopherSho said:
thanks for the logs..
So we have some good news and interesting news. from the 275+ seconds (WoT)
Both TQ-converters 'behave' in the logs the same. Assumption, there fine.
RPM curves are basically the same, so the 'power' is the same. IE it is able to make' the requested power.
BUT ::
yours 100% has a fueling issue. Your OAR keeps fluttering. His is rock steady.
Yours has much larger more abrupt spikes in throttle blade position under WoT, unsure about the meaning at this time but it is a very noticeable metric
Yours has LTFT elevated under WoT as compared to your fathers rig, in particular Bank#1 .. its only .5 off... but it is a difference to note and again points to a fueling issue
STFT are both erratic .. still sorting that out
YOUR waste-gates are operating 10% higher when ramping to 3rd gear, i seem to recall you have rebuilt yours so it is a metric id discount.. but noted
Both have solid AFR so the ecu in yours is doing its job to maintain proper mix.. but the fluttering OAR is suspicious. I am surprised the tuner did not comment on it ..
so not the TQ-converter or sending unit. this looks like it is going backwards to a fueling issue, or a issue with the intercooler having A LOT LOT LOT of flammable goop in it.
Out of curiosity ... how much oil are you putting in the truck between oil changes?

Thank you so much for comparing these and getting back to me. Like i said i dont know how to read them so i appreciate you taking the time to do so. A fuel issue has been in my mind but wasnt sure about it or what to look for. Also good to hear on the TQ converter, was really hoping it wasnt tranny related as from my research these transmissions have no external sensors or modules. Everything is internal in the lead frame.TopherSho said:thanks for the logs..

Oil changes are every 5000 miles religiously, usually even a couple 100 miles before i reach the 5000. I did pull the intercooler again last week to take a look, and there was some oil in it, but no more then what it was when i swapped it out for the wagner a year ago.
I will add this, back when this all started prior to finding all the water in my intercooler that caused the misfire, i did dump a bottle of heet in thinking maybe i possibly got a bad batch of fuel. That made no difference so i made sure to run a full tank through. After that tank, i dumped a bottle of techron in to see if that would change anything. Of course it did not, but could i have created the problem by doing this?

No sir, Those additives are very flammable, they would not affect the OAR like this with the ratio of fluids. HEET is meth, our engines love meth until it is to much for the fuel system and have different issues. Are you buying the same gas as whats in the other rig?
I wonder .. hey Z/SHOdded has anyone reported issues with the data/voltage from Ethanol sensors? Where would you look to check the harness? ..
EDIT; I don't have access to it, but I think there is a PID fore the Ethanol sensor .. have the tuner add it in and relog.
Both of us run sunoco fuel from all the different stations around here. He runs 87 octane and i have used 89 for the past 3 years being mine was tuned for 89. Currently im not actively working with the tuner on this since its im having the problem on the stock tune, and when i first noticed the problem and sent a log, all i got back was a revision to try with no explanation or acknowledgement of the issue. Im not bad mouthing anyone by any means but i felt it was clear i was on my own with this one. I could look for an ethanol pid and see if it shows anything, but ive never seen it mentioned or ever heard of it on the f150s as well.TopherSho said:
So any ideas on where to start or what to do now at this point? Could this explain why my turbos are much louder but yet being limited to 7lbs when not under wot? Or do i just still have a really bad batch of fuel in my tank? I didnt see a pid for the high pressure fuel pump. Could there be something wrong with it causing these problems? I appreciate all the help guys.
the OAR value should not drop like that, could it be bad gas? maybe? But I assume you have been fueling more than once recently so I think the likelihood is less for bad fuel. To much Ethanol is a possibility, but you would have to run north of E30 to see it, and as soon as you fueled up again with 92 it would resolve.
With the comment from SHOdded that you may not have a true flexfuel sensor for that year were back to possible O2 sensors.. your cats seemed fine as compared to your fathers. O2's they play a large role in determining fuel 'type'. are you 100% certain the dealer really replaced the o2's and did they do the fronts AND back ?

Uh the dealer hasnt touched anything on the truck other then the reprogramming. Everything thats been swapped/changed was done by me so the o2s are the originals. Ill pull them this weekend to take a look and clean them. Plenty tanks of fuel have been ran through since the beginning of this so i dont foresee it being bad fuel either.TopherSho said:

Sorry on the parts touching
.. I remember now that you did the hardware. In my head cleaning my help, but if the tips are embedded with debris or the voltage coming out of them is out of range the ECU may still be doing the unusual adjustments. Im still a bit perplexed with the throttle actual behavior but the OAR sinking like a rock is all we have to go on :/Its all good and again i greatly appreciate all the help. Maybe the water indigestion and misfire caused the o2s to get out of sync i dont know. I really wish it would throw a code. It would make me feel alot better if the truck knew there was a problem going on. I did try my dads throttle body awhile back thinking maybe a throttle position sensor issue, but of course it didnt change anything.TopherSho said:Defhd10 said:

Decided im not going to touch the o2s. Atleast not yet. Im not getting any codes associated with them like i should if they were a problem, and i dont want to ruin them by attempting to clean. To the point now im going to run it until it throws a code or a rod. Really dont care at this point. Ive wasted so much time and money and not one single thing i do makes any bit of improvement. Really appreciate all the help guys, but ive pretty much given up. If i knew what it was i wouldnt have a problem spending the money to fix it, but im done wasting my money on the things that wont fix it.
I'd be very careful tossing a rod, if the dealership/ford network/warranty-company has you marked down as 'modified' they will not honor a engine rebuild. I ran into that with my Bad injector taking my block out. I had to pay out of pocket.
Understand the frustration though...
