Idle log: Giving the car a little bit of gas at idle here, not too sure what to look for here but I see the voltage dropping super low as the car almost stalls.

Driving log: Not sure if there's anything else to look for here. There are a couple points in time where I almost stall highlighted by the voltage dip.

I'm super new to all of this and will take any pointers or suggestions. |
Ok in the log at idle with no throttle the target afr is round 14.7 which it should be, but the actual afr or measured afr varies rich to lean. This seems bogus as in a few places the actual afr is measuring 20or close to 20this is heavily max lean, but the injection times from the port and direct are not zero. Most likely cause is bad 02 sensor the front 02,or possib Y intake or exhaust leak. Also check the direct injection computer has all three mount bolts in and tight
