Car is a 1991 Accord LX. Need opinions before spending money on replacing parts that I don't even need. Please be specific.

If it has an exhaust gas recirculation system, yes.

I can cause problems if there is a blockage not allowing the exhaust to escape. How does the vehicle run at other times? On highway, at full throttle, etc? If you have low idle and also a misfire, I would fault air management, such as Mass air flow, Idle air solenoid, or more likely to cause an idle problem with a misfire is a vacuum leak. Is the check engine light on? How long has it been since you had new plugs and wires installed? These could also cause misfires and poor idle quality.
Update: Since the check engine light is on, there is a problem in the engine management system. You will need to take it in to be checked on a diagnostic machine. Either the dealer or another reputable repair shop. The code stored in the computer will help to diagnose the concern. A misfire and low idle could be caused by many different things. The fact that the check engine light is on and a code is stored will help to diagnose the concern.

It is possible, but not likely because you would also notice other signs and symptoms as well.
Easiest way to satisfy your mind about it is to disconnect the exhaust pipe at the manifold and then start it and see if it runs any different.
BE WARNED---> It will be loud when you do this. It will also cause other long-term problems so don't leave it that way.
It is most likely something else, such as A/C on (it's warm out)
Does it do it all the time, or just when cold? If only when cold, the cold idle air bleed piston may be stuck. Hondas and some Acuras of that vintage do that.
You may be looking for other things, but for things that "just start to happen" all by themselves, those are the most frequent.

Yes. Exhaust flow needs to be regulated (back-flow) and remember when modifying exhaust you do the following, change flow rate and temperature . The smother the exhaust flow the faster you can cram in more air/fuel mixture and then you would have to adjust timing etc..
However that is only one of the many things that can affect misfire/idle.

A partially or completely clogged catalytic converter can definitely affect engine performance. Think of it the same as someone shoving a potato or banana up your tailpipe. The car won't crank.

Yes. Improper back-pressure can cause problems with how an engine runs.

Go to the local muffler shop and have a flow test done, cheap place to start...
