A&E Results.. need advice

[dieselsubmariner]

first of all.. my truck runs really rough when cold and has no power.
already changed injector o-rings, icp, and rebuild ipr. Got new oil, and all filter.
New GPR as well

Now:
i had my PCM re-flashed yesterday at the Ford Dealer, so the A & E Software works.(my truck is a late 95).
Ford Dealer said, my idm throws an error and is bad..

Today we connected with the A&E Software.

Did Buzz-test and first test, 4 cylinders did not buzz and had an idm error. did a second test, just to make sure and only #3 did not buzz.

We changed the IDM with a newer one from a 97 4x4 F250, just to test.
Now #3 did not fire right.
cranked the truck (ran better) went on test drive.

HPOP at idle is at 567
at wot it holds steady between 2500 and 2470.

exhaust back pressure is 17 at idle, tops out at 35 at wot
manifold pressure is 16 at idle and 30 at wot.

The CCT test came back with P0266 (cylinder fault #2) and P0272 (cylinder fault #4)

did a Buzz test, once we stopped and all cylinders were fine.
Installed my old IDM, all injectors buzzed, but still get IDM failure.


Please advise on all data and what to replace .
btw.. i was thinking of replacing the uvch.

if you guys think i need an IDM, any source ? anybody has one ? or should can I go used at a salvage place?

[dieselsubmariner]

i plan on purchasing some parts today, so they arrive in time for the long weekend.

any advice..

i also plan on replacing the down pipe

Have you pulled the connectors off the VC ports and looked in? All the pins are bright and shiny and not burned? No oil in the VC connections? If you are looking at a JY for IDMs get it from a Super Duty and not an OBS.

when i had the injectors out, i noticed all plugs were wet inside.. should they in fact be dry ?

[swalker332]

it sounds like you uvh's are bad. with everything you posted its not engine based.

[dieselsubmariner]

that is what i hope it only might be. i went and ordered two new ones with pick tails and hope to get them for the upcoming weekend. Just wonder now, if i will still see an IDM failure.. hopefully not though.

once everything is working again , i will try my bullydog 6 pos chip, that i pulled at the beginning of all my trouble shooting.
I also will replace soon my stock down pipe, remove the ebpr valve and go straight pipe :-)

[swalker332]

after you replace the harnesses you shouldnt get an idm failure any more. 99% of the time when the idm fails the truck doesnt start at all.

[swalker332]

let us know what happens, and what you find.

[dieselsubmariner]

i sure will post an entire report here of all my findings, once i’m done.

thanks
