Surging car

Surging can be caused by many things. One is the level of the coolant in the system. Also make sure that there are no air pockets in the system, use the bleeders to remove any. Given the age of the vehicle, it could be the IAC (idle air control) valve. But yet another possibility is the intake manifold gasket. A small leak there and the engine struggles to maintain an idle, it can also cause the other symptoms.

I would look to the intake area. Ignitor or distributor would show different symptoms, for example just turning it off as you said and restarting it tends to clear the problem.

I have found that the cure for this problem is not always easy. Some people point to the O2 sensor but unless you have a check engine light on that points in that direction it has to be injector/intake related. On that old of a honda I would look at the air intake sensor. It is located across from the throttle cam on the intake. (The cam that the gas pedal cable attaches to) This can stick, I have gotten some WD40 to work into this and fix the problem. However, the sensor is riveted on to the throttle body. I have taken the rivets off with a file and then cleaned the sensor and put it back on with screws and had it work fine too. Otherwise the replacement of the throttle body is necessary.

Don't forget to check all of the vacuum hoses looking for connection, holes, cracks, etc.
