Engine Performance problem
1998 Nissan Maxima 6 cyl Front Wheel Drive Automatic 160k miles

I have a 98 nissan maxima with 160k miles and it's misfiring badly. I got it diagnosed and they said its a cylender 3 misfire, so i changed my coil packs with 3 and 1 and now it says multiple misfire. i just changed all my plugs and its still doing it. It was also misfiring before i changed my new plugs..

Engine running rough or misfiring can be cause by the following:
1.Defective spark plug.
2.Inadequate spark/coil,defective spark plug wire.
3.Lack of compression
4.False air leakage.
5.Faulty fuel injectors.
6.Insufficient fuel pressure.
7.Contaminated fuel.
8.EGR valve that is leaking.
9.Oxygen sensors.
