I’ve got an NB8A. Manual.
When I was on the freeway today going about 100kms and sitting at constant revs, the revs would suddenly dip and then resume back every now and then. This would happen now and then while on the freeway. I hadn’t noticed it at lower speeds.
Any clues as to what it might be?

RPMs dip momentarily then bounce back up while on 5th gear.

Wow. Man. Thank you. My mechanic said the wiring to the crank angle sensor was melted, grounding etc. (Sorry I don't have a mechanical background).
But it's fixed now cheers.
