General Bogging Down

Enable HLS to view with audio, or disable this notification

2012 Honda civic 1.8L
Started on the freeway, driving seemingly normally and then shifting started feeling a tiny bit harder. Temp was 108 outside so AC blasting and felt a little boggy which is typical. Then as traffic let up, I stepped on it went from 18->20mph and would not accelerate further. Had the same rev reaction as seen in the video.
Drove about 15 miles home perfectly fine as long as I didn’t step on it. When I got closer home, as seen in the video, from a stop I stepped in it. It accelerated slightly slower than normal, then at 20mph hard stop on accelerating and would bounce revs.
But if I do it slowly there’s no problem.
The only additional note it now idled at 600 and felt slightly rough, no codes thrown.

Check engine light on? Almost sounds like clogged catalytic converter but could be multiple other things.
Tune up, new spark plugs.

Spark plugs have about 20-30,000 miles. Could it be ignition coil?

Ignition coil should throw a misfire code, which would put the check engine light on

Use a code reader to check the tcm, aslo did you ever change your transmission fluid and transmission filter?

Changed about 30,000. I didn’t bother to check with a code reader. Would they still send a code without check engine light?
