what would cause O2 sensors not to work??
Why are you determined to use a part number for a z06 is it because it sounds cool?
Do you have a check engine light?
Are they a hack job wired in?
You can use a scanner to display the outputs to see if they are working?
So why are you after your 02's did they **** you off?
Check out the fuse that operates the heater circuit. Not sure which one it is, and I think it is shared by another function. Good luck.
