Thanks for the welcome.
i thought thats what i read about aftermarket sensors compared to oem.

just to make sure before spending the money on a o2.i unhooked the battery for an hour and cleaned the buildup of the white/green powdery crud off the terminals.
took it for a 20min spin,and so far no check engine light.

so right now im going to wait to see if it comes back or stays off.
