A&E Results.. need advice
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
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.
