I never had any idle problems with mine. Does it have an idle adjustment screw? Might be some kind of a vacuum leak. I know they can screw up the idle. If it has an IAC I would also check that.
If it acts like it missing when firing it may need new plugs and wires.
As part of the tune up you will need to replace the distributor cap and rotor assembly too. It is really easy for anyone to do and it only costs about $45 for the cap and rotor.
