I was checking my car for codes with the OBDLink, and when I checked the "On-board Monitoring", I saw this:

Are the cylinders actually misfiring? I haven't had any codes or anything.

The reason I originally checked was because I thought I felt a very very tiny "pause" when I accelerated, but nothing I thought to be that significant.

Has anyone ever used the "on-board monitoring", on the OBDLink app, that can elaborate?

Thatā€™s normal. All cars Iā€™ve owned have had occasional misfires in that range. My Supra included. Nothing to be worried aboutā€¦ unless itā€™s an Audi S3 engine that has over 50 misfires in a 15 minute driveā€¦

I did a quick 2 minute drive to test the mass flow sensor and it had no reading:

I also checked the o2 sensor #1 and it had no voltage:

Is any of this normal?

That makes me feel a bit better. I'm still curious if the MAF sensor is something I should look at. I put a brand new K&N filter over a month ago, and I noticed today that it released a lot of oil (bottom of the airbox). Fortunately, there was no sign of any going towards the engine , but maybe the oil vapors could damage the MAF sensor?

Again there's no code that the car is showing, so everything appears "allright". I just get nervous when there's anything even slightly off

99% of the time randomly pulling codes and hunting for problems when there is no CEL or drivability issues will just have you scratching your hear and running in circles. There would be an check engine light and serious problems if your sensors actually stopped working.

True, thanks for clearing that up!
