2002 Infiniti qx4 started makimg a knocking noise when started, goes away when reved up

What is your question?

Last Saturday drove infiniti all day and was fine, come out of store that night and started the car,it started knocking. Sound goes away when gas pedal pushed in to speed up. It makes the knocking sound as soon as started, while idling, amd when driving until revving engine. I haven't driven it since.

What makes this problem better or worse?

Revving up/speeding up makes noise stop

How long has your 2002 INFINITI QX4 had this problem?

Started a week ago, haven't driven since
