Have it scanned to see which cylinder is misfiring.I have seen injectors, coils and cylinder heads (depending on what engine) go bad on those cars. Start with a scan to see where to start, then pull that plug and look at it. Also test the spark to that cylinder. Use carb cleaner and carefully spray at the back of theintake near the firewall for vacuum leaks, if the engine changes idle, you have sprayed a leak.
