I just took my '97 grandprix(gtp-3.8L supercharged )to autozone to be scanned for a service engine soon light. The code that came up was P0302 - cyclinder 2 misfire. The car has 103k miles and had the spark plugs , spark plug wires and the 3,6 igintion coil replaced 15-20k miles ago. Any suggestions where I should check first for the problem?

"had the spark plugs , spark plug wires and the 3,6 igintion coil replaced 15-20k miles ago" well since you had those replaced and now its a misfire on #2 then replace the #2spark plug wires on that one now. also where are the plugs gapped at?
