i have been feeling the car have a slight rough idle at a stop. but nothing major so i didnt do anything.

but today i noticed that the when stopped the idle was at 500 poss. 400. Isnt that kind of low.

What could be the problem. spark plugs and wires and a new cap?

car is a 1994 integra ls.

Thanks!

adjust the idle screw at the manifold
if that doesn't work, then clean
out your idle air control valve
in the back of your intake manifold
