Pull plug, attach to wire and ground to block, crank engine, look for blue snapping spark.

I had this same problem with my grand am same year same engine. The mechanic told me there was a very small leak in the gas line and air was getting into the line. Said there was nothing to worry about unless the car dramatically decreases performance.
