Two power grounds come out of the harness, to a connector (if it is still there), and should be terminated at the battery negative. If this doesn't solve your problem, you should start your own thread.

In this picture, the two ground wires were incorrectly connected to the O2 sensor harness. They should go to the battery negative.
