Just a thought...
Could explain the 73 and 23 error codes.
When you tested the TPS sensor was it attached to the TB?
While working on a friends car I noticed that some of the nylon bushing for the TPS sensor where it fits to the throttle butterfly valve stem was damaged. There was also a bushing that had become deformed and broken.
You might re-inspect the TPS mounting to the TB to make sure it is mounted so that the sensor moves as the throttle is opened. I have noticed on my TPS for a 5.0 engine that the TPS could be mounted so that the butterfly valve shaft would not mate properly with the TPS sensor (In other word, the throttle would turn the the butterfly valve, but the shaft of the TB would not turn the TPS).
If you just tested the sensor, not mounted to the TB, it may be that the mounting tabs did not align properly when installed?
