a 98 Honda civic should not have a carburetor. it is a fuel injected vehical. in this case there might be a screw that you can adjust the idle with. have someone watch the engine as you pump the gas. the engine can be off when you do this. they will show you the arm, of lever that moved. when it sits all the way down (gas pedal off all the way) it will stop on a screw. turning it right = idle up, turn left (counterclockwise) = idle down. but mostlikely everything is all electric and a shop will have to adjust it with a computer.
