i will load update log file. o2 bank 1 sensor 1 is staying close to .45 the whole time. i didnt save new log file unfortunately

You don't have to save a log file. It it saved automatically upon stopping it, with a name based upon date/time.

why is this data log useless? the vehicle isnt running because i was seeing the voltage changed of o2 sensors plugged up and unpluged

becuase for us behind a tiny phone screen, trying to help you, a non running log/scan is useless for us to give any suggestions.

Something is wrogn with your O2s. a ground, shorted wire, pinned incorreclty, i dont know, but you need to figure that out before doing anything else.
On one of your logs the ltft was give 25% and stft 50%.. i didnt even know thats possible. You have a mechanical issue, a vacuum leak, bad O2s or wiring, exhaust leak, something is going on. That needs to get fixed first.
