Engine pinging

Hi all
My 99 D2 pings a little. Usually when not up to full operating temp. So I baby it until then. No codes ever. Running premium. What sensors could be causing this without throwing a code? I know it could be the knock sensor but could it be O2 sensors? And I do have the correct plugs. Also I don't believe there is any carbon buildup. Thoughts and Ideas please.

It is definitely pinging! Also I have been having this problem for quite some time. Many different gas stations. Engine was rebuilt at 87k with top hat liners. Currently I have 113k.
