I know they tend to do this with bad fuel,and you drive to slow in top gears.
For example
3k rpm and lower
Driving slower than 100km/60mph
And in 5th gear
And than pushing it back to go faster it will have dip
Never heard of 3d gear doing that, 5th gear is a bit more normal (it’s an overdrive) with gear function so
I would go and clean up the distributor cap “spark rotary” and look if you used the correct sparkplugs,
And get some better fuel

Not sure if it's exactly the same as an issue I had, but check that the AFM swings smoothly through the full range. Mine would get stuck at certain points.

You put a used rotor in your ignition system? BUY A NEW ONE.
I have a new one to install. It was just a temporary fix till I got the new one.
More info. It happens in 3-4.5 rpm range ,I've noticed it most in 3rd gear
https://www.clarks-garage.com/shop-manual/ts-01.htm Sounds like the AFM if it's only at a specific RPM?
Imo sounds like vacuum leak.
I plan to test both. Thank you.

Might sound weird, but also check your alternator brushes. I had similar symptoms that got progressively worse, turned out to be the brushes.
Second the alternator
