Engine knock

Jul 13, 2005 2 Replies

On my 2002 Maxima, I have this mysterious engine knock happening under acceleration only if the RPM's are at 2000+/- 100. The dealer changed O2 sensor and air flow sensor and still the same. I always use premium. Does anybody have any ideas?



Does the noise increase or decrease with engine temp? Stick or auto?

Once the temp is at normal, it becomes present. It's auto.
