My accord has a problem with the tach jumping. Periodically when I press on the gas the tach will bounce around. Lately it's been bouncing and dipping. When it dips it sounds like it's bogging out and going to stall. I can't figure out if it's an igintion problem or the distributor.

Tach bouncing and engine stumbles are usually a sign of a coil shorting out.
On your car I'd replace both Coil and Ignitor, as well as replace the plugs if they have a super sized gap and rounded off electrode

 

I'm looking at my Chilton's book and it doesn't mention anything about a ignition coil or ignitor. It has a self timing distributor.

It's a 1991 Accord LX.

 

could be the speed sensor, my buddies '90 used to do that, it would move around or sit at 0. can't remember if his engine stumbled

 

likely the dizzy, ignition wires etc..

 

Friend had the same problem, Changed the coil ( his is a 92 dx) changed the coil and it still bounced around, so he changed the dizzy and the problem went away
