For a 2000 Mazda 626, the spark plugs are located underneath the engine manifold. In order to remove these, you must first remove the spark plug wire boots by turning upward in a left to right motion. Afterward, use an insulated spark plug socket, extention and driver to remove the spark plugs are they are inches beneath the manifold. Be sure to properly gap the spark plugs, use anti-seize compound, and properly re-attach the spark plug wire boots.

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
