2002 Chevy Malibu 4 cyl Front Wheel Drive Automatic

Took my 2002 Chevy Malibu to AutoZone yesterday. Diagnostic test indicated "multiple cylinder misfirings". Any suggestions on how to fix this?

Misfires can be caused by worn or fouled spark plugs, a weak spark (weak coil, bad spark plug wire), loss of compression, vacuum leaks, anything that causes an unusually lean fuel mixture (lean misfire), an EGR valve that is stuck open, dirty fuel injectors, low fuel pressure, or even bad fuel
