If not this is the probably the reason for the light on your dash. If you did not re-install your post cat 02's or even got them mixed up and installed a front 02 in the back or vise versa this may also turn on a light. Your front(before cats) O2's see a varying O2 content, rich/lean/rich/lean,etc but your rear(after cats) O2's want to see a constant 02 content, if the computer sees too much "activity" on the rear 02's it will turn on the light.
