Very good suggestions so far. Also, if the car is a MAF system, a vacuum leak will make them run like crud. Check the ducting between the MAF and throttle body. For that matter, a MAP system will also act weird if a vacuum leak exists. A bad MAP sensor can also cause problems. If your system is MAP based, look for a diagnostic procedure in just about any service manual (haynes for example). Whatever you do, don't just throw parts at it. The manuals will explain how to check the sensors. Shotgunning can get very expensive on a fuel injected car.
