2004 XLT at the Crossroads

"Hybrid Electronic Cluster" has to do with the Instrument Cluster.
It communicates with the PCM and PATS (key security system).
To fix the ReadinessTests you have to do a drive cycle.
I don't have time today to look up the codes and see what may be wrong.
Probably tomorrow.
How much of your old engine did you use on your new/used engine?
Injectors?
If not, the injectors may be leaking (my first guess on too rich).
How about sensors?

I did move the known good injectors from the original engine over with new seals. I haven’t done a drive cycle yet because it was idling rough, just a few short drives for parts and to drop it off at the mechanic. I cleared the P2196 with a new purge valve but it was still running so rich with black smoke staining the driveway. I didn’t move the fuel injection pressure sensor but now wishing I had moved the fuel rail with the sensor and regulator at the input end. Thanks for all your feedback!

Hi Larry. You might try changing all your 02 sensors and check your manifold to exhaust and block for leaks. Make sure all connectors are free of corrosion. It's a shot in the dark but it might help.
