PROBLEMS WITH KNOCK SENSOR A

2004 Nissan Xterra

Engine Performance problem
2004 Nissan Xterra 6 cyl Four Wheel Drive Automatic 85,000 miles

I have taken my xterra back to my usual mechanic to have the check engine soon light diagnosed twice. It came back as knock sensor, o2 sensor and number 6 cylinder misfire. It has idled kinda rough since I bought it two years ago. I have replaced wires and distributor. The plugs looked fine. Has any one else had any problems like this?
