Rough idle

Got a 91 Legacy Turbo 5MT with 141K. The car drives fine but sometime while idling the rpm would just drop and start idling really roughly. Any ideas on what could be wrong?

Thanks
Sam

Spark plugs, spark plug wires, air filter, fuel filters. Change ALL of these and reset the ECU and see where you are after a day or two.
