"Wouldn't it be more pronounced at higher rpms such as at the top of 2nd or 3rd gear though instead of such a short period of time mid-rpm in 1st gear?"

It would be consistent in each gear. RPM may vary but the affect would still present itself.

As stated, something is telling the ECU its lean or has an extreme temp cold or hot. ECT or IAT sensor.

You could have a wonky O2, but one would presume it would be consistent regardless of gear.

Look through your IAT, O2 & ECT data. You are looking for a blip leading up to & including the problematic area as the issue is only occurring for a brief.
