It probably needs a tune up. My 1998 Mazda 626 was idling very rough, so I did a tune-up by replacing the spark plugs and wires. This made the engine run better, but the rought idling continued. I took it to my mechanic, and he found a vacuum leak somewhere, and $270 later, it idles smooth as glass
