Please help! I have a Nissan Maxima 1999 with a reoccuring code of p0325, knock sensor bank 1..not sure which on that engine is bank 1. Front or rear? Any tips on doing the job or where the sensor is located would be appreciated. The vehicle is sluggish at times and has a jolting sensation when stopped and in drive, and pings if I use less than 93 octane.. I believe all the symptoms are related, as a power balance test has indicated no missfire. Thank you for your time.
