Re: Problem with all o2 sensors?
It appers they all use the same G101, and they all use the same splice 146 to the ground. I would inspect all your grounds and make sure they are clean and tight.
S146 is in the harness on the right side of the bellhousing approx 3-6 inches from the engine.
G101 is right near the battery.
