lets see if this works

 

You have some data there that someone more knowledgeable than me should be able to make something of. I see where it shuts down on you but I don't see why. Have you checked all of your connections and wiring?

 

well I was getting a cps code so I swapped it with my spare and cleared the codes. went for a drive and no change( died once in a hour long trip and several stumbles).
the codes I got after trip are. B1352 ignition key in circuit fault, B1450 wiper wash/delay switch circuit failure, P1876 transfer case 2-wheel drive solenoid failure, P1212 icp lower than desired, P1247 turbocharger boost psi low. any of those able to cause my issues? also noticed sometimes when I go to take off from a stop there's a 2-3 sec lag from when I hit accelerator till the truck takes off. is it possible for the accelerator switch or maybe the idm to cause this stumbling and dying? it's been failing #5 on cc test, but I tried to check it last night after swaping the cps and the test wouldn't work. just kept saying test fail unknown cause.

 

The ICP lower than desired could do it but I don't see what's causing that. Hopefully someone who's skilled on that will pop in.I get that transfer case solenoid failure all the time and have heard of others having it as well. I have key in ignition fault too but that's because my wire there came unglued one time and I never glued it back on, that just stops an annoying gonger from gonging now. Have you checked all of your wires for fraying, tight connections and the rubbing through issue where the harness rubs on the driver's side VC?

 

well I've just about lost my patience with the truck so I'm going to throw a couple parts at it. according to the tech at the dealership about all that's left for me to change is the throttle sensor and the idm. so I'm thinking I'll just change them. any recommendations on where to get them. the dealer wants almost $500 for the throttle sensor. I'm not paying that, so any suggestions

 

Here's some part numbers to check out for your TPS...

1C3Z 9F836 BA or EC3Z 9F836 A [RockAuto $139.99]

F4SZ 9B989 AA [$57.10 @ Ebay]

2C3Z 9F836 DE [$577.79]

 

I believe Walleye is on the right track. I recently went thru a very similar experience as what you've described, and it ended up being 2 issues.
1. I had 2 bad orings on my passenger side bank injectors.
2. I had a bad UVCH on the passenger side as well.
I figured since my UVCH's were new and my truck only had 15K on the new build it couldn't possibly be the UVCH's, but it was exactly that. It caused me quite a bit of anguish. The UVCH's are much cheaper than the IDM, so if I was in your shoes, I would definitely start there.
My truck would run fine at times, then it would buck & stall out/die and sometimes it would restart, and other times it wouldn't. Again I could go weeks, with nothing happening, and then the issue would start all over again. I thought just as you did, that it had to be the IDM. You see, I had already replaced both Ipr's the icp & TPS as well. So after all of this, my next step was to visually inspect the wire harness from the Injectors back to the IDM. When this to yielded nothing, I decided to go back to the IDM. I removed the component plug and pinned every Injector with an ohm meter and this to yielded nothing. This led me to believe it was in fact the IDM. I took it to a shop to double check my findings before I spent the money on an IDM. Again, they chased it down to the UVCH. It acted so intermittent that I never suspected the UVCH could cause this. So Yeah, it kicked my butt trying to figure it out.

 

well I swapped the tps with an oreillys one and it ran better for about half a day then died and would not start. while cranking it I noticed my oil pressure gauge wouldn't come up so I started thinking I had a bad lpop. I just got it swapped and got it to fire up and took it for a drive. no change. called the dealer and they have the uvch in stock $100 per side. i'll give them a try cause I'm out of ideas. could the harness cause the low ipr? cause those are about the only codes I'm getting.

 

I had a sticking IPR give me fits twice; both times it was the same result. The engine would stumble randomly at any speed or throttle position, eventually becoming a shutoff. The first time this happened I went with a rebuild kit, several years later it started happening again. That time I took it apart and cleaned everything and put it back in, and it worked better, but I still had issues occasionally. A new IPR has been going fine since. The rebuild kits don't address any potential issues with the solenoid portion of it, so I think that was my problem the second time.

 

ipr is new motorcraft unit

 

Without reading or remembering everything else here, how's your oil level?

 

full, I check it every morning. it does use some oil. I've never figured out where its going. no leaks, no smoke, and not much blow by. I drive a 100+ miles a day and sometime i'll loose a half quart.

 

changed the uvch on both sides, and was still idling a little off. I still need to put the vc's back on so I can do a road test but I'm not very hopeful. it got to hot so I called it a day. what's the chances of the hpop going bad and not being able to keep the psi up when everything is hot and ambient temp is pushing 100. the truck seems to get worse later in the day as the heat climbs.

 

I'm loosing my mind! I got the truck back together this morning and hooked up my AE and ran codes first thing. I got a P0603 which is a PCM memory code. I figured it was from disconnecting the - on the batteries. I cleared it and tried to start the truck. the truck almost started, then AE lost connection and truck died. I reconnected the AE and ran codes again and got P1670 which is a bad connection between the PCM and the IDM. cleared it and started the truck. in a 10 min. trip to the store it died 6-8 times. ran the code when I got back and the P0603 was back. so far I have changed 8 injectors, 2 ford CPS, ford IPR, NAPA ICP( runs the same with original ford and NAPA) melling lpop, and both ford UVCH. I recorded the run with the AE so if someone can look at it and glean anything useful I'd appreciate it tons. I'm down to either the PCM, IDM, or the hpop, being the issue. that all that's left.

 

bump, still hoping someone has some more ideas
