I did swap the temp sensor back and the pinging came back. I would definetly try it before doing the plug swap.
I have no pinging anymore w/ 91 octane fuel or better.
I have a very slight pinging still at just the right amount of throttle (about 1/4) and the right amount of load (slight hill climb) w/ 87 octane fuel.
The temp sensor is cheap and well worth the try.

Someone should make this a sticky. Amazing info here from some "real" experts. I think pinging is one of the worst things that plague vettes, just look at how many threads are on this subject. I went thru the same stuff here and basically did everything - except for the temp sensor. That is PURE GENIUS ! I too have that dreaded 40-50 mph ping when you lug the engine....just enough to increase a little speed but not enough to cause a 4-3 downshift. Very annoying. At work, I am the "king of ping" cause thats all I complain about. LOL
