Dan is right. If the engine idled that slow it would stall and cut out. DO you mean it idles at 2000RPM that would be way too fast. If the idle is too low look at the air boot from the air filter housing to the manifold make sure it is in tact, (no rips) , and no other vacuum leaks around the intake manifold, clean the throttle butterfly by removing the air boot, open the butterfly by hand and using an old tooth brush and Chemtool remove carbon black deposits from the butterfly area.
The 2.2L and 2.0L turbo electronically adjust the idle speed, the 1.6 L you can adjust the idle speed by turning the idle speed screw at the forward top side of the manifold but need to follow specific instructions. Autozone have some popular workshop manuals for free on line once you register (for free) on their website There is also a company that independent auto repair shops buy their information from that the same information inexpensively to do it yourselfers. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate

Sounds like your rpm gauge or tachometer may not be reading correctly, your car would not run at 200, it would die, the starter alone will spin it at about 350 rpm.
