It has been a while but here are the updates.
So instead of shooting in the dark I bought AE software and did the scanning and testing myself.
results showing a high to low side code on cylinders 1,2, and 8. contribution test showing cylinder 3, 4, and 5 failing. As well as P1316 the IDM code error.
So I took the VC back off. started the vehical the injectors are spitting oil like normal and nothing visibly wrong so none of them are totally dead. I did an Ohm test...all the pinouts were within .2 ohms from eachother and all within the Ford specified range. This leads me to believe there is nothing wrong with the wiring from the IDM plug through the harness into the injector harnesses, solenoids and back.
Buzz test checked out fine.
so I put it all back together and replace the grey CPS with a dark blue/purple one seems to be running the same, although initially(cold engine) the contribution test only shows cylinder 3 failing. I have to run the test with a warm engine and see if anything has actually changed.
I seem to be running out of ideas. Everything I have tried with the wiring has checked out. I have been told that the compression test shouldnt be an issue in my case as I am not losing any oil and there is no smoke as would be evident from oil slipping past the rings and out the exhaust.
So finally I broke down and ordered a new IDM, although I dont believe that to be the issue.
Any ideas, suggestions, or comments would be appreciated. If the IDM does nothing I guess I will be replacing injectors and at that time I will do a compression test since I will be right there.
