A few more detail about it may help us develop some theories.
Like, when does it happen. Warm/Cold?
A/c on/off or other accessories on/off
When you first start the car?
Year and miles on your civic

with hondas a lot of the times it is the FITV (fast idle thermo valve) or the IACV(Idle air control valve).

here's a good write up on how to clean your FITV

i say the fast idle thermo valve. thats the problem i had. some times the wax leaks out and just bounces constantly enven after it warms up

and if that doesn't do it, try the intake manifold gasket or throttle body gasket. Spray some carb cleaner around those two gasket and if your engine revs or stumbles, you'll know where the problem is.
