Re: scan files
Do you look at these at all? You have 5 codes. I expect 26 - EVAP solenoid; 27 - EGR solenoid; and 29 - AIR pump circuit are due to deletions. But you have DTC 23 for an open circuit in the IAT sensor (reading 40-deg below zero), and DTC 48 for an open circuit on the MAF sensor (reading 470 gps).

Re: scan files
When the MAF sensor fails (or is removed), the PCM defaults to the "speed-density" method of calculating mass air flow. The critical sensor inputs to a speed-density system are MAP and IAT. You have no IAT sensor signal. I'm amazed that a miss at 70-80% throttle is the only problem you have.
At a minimum, you have to fix either the IAT or the MAF. It isn't even worth looking any further at the log at this point. Is you IAT sensor even installed and connected?

It's not going to find itself.
