So first, make sure your AE setup is right, it needs to be configured and if you put the sw in your computer to use it, it may not be (it also needs to have the Ford Enhanced Package to read many codes like from the IDM)


What you describe sounds like an IDM/UVCH problem to me. Running "really rough" is often running on just one side because of a bad UVCH connection (if you can get it to run at all, the Temp difference in the ex manifolds is obvious). Sometimes as simple as wires chafed against the dr side valvecover as they run to the pass side UVCH)

Be sure your able to get a proper scan from the AE, see if there are really codes there, with a an Enhanced Powertrain scan, there surely would be something (eve if just some Body codes that aren't part of this ;) )

Have you looked at the Wiring at all?

We have a common issue where, as the bundle of wires go from the 42-pin connector, to the UVCH, and routed Over the dr side valvecover, they will chafe against the valvecover. Underneath the bundle you might find spots where the insulation has warn-away and be giving you intermittent shorts.
