DTC - 22 Throttle position sensor error (signal low)
DTC - 34 MAP sensor circuit error (signal low indicating high vacuum)
The other is O2 sense lean which would be a result
I would look for a break in the VRef wire for the two sensors On the CFI I troubleshot a few years ago they were adjacent in the engine wiring harness.
