Better earthing point for a V8 02 CTS

[undar8ed1]

The earthing point on the back of the passenger side head for the 02 sensor and CTS/TPS is there a better spot I can use? I`m getting fustrated as I`ve cleaned it and freshend the connections and still has the same codes indicting a bad earth problem had the exact same codes on my girlfreinds V6 and just cleaning them fixed the problem. So I`ve seen a how-to for moving the ones on the V6 to the engine cover studs but what about the V8, any one got any strong earthing point suggestions? I wan`t to tackle it this W/E
and my RDO tommorow

is there an chain mount point at the back of the engine there at all you can use? im not too familiar with the 8 for mounting points.

What might be a benefit to you whilst tackling eathing points, is to get some extra wiring and do a hot earth kit which should improve the earthing problem.

have u upgraded the earth wire that goes from ur battery to the motor, they have alot of problems with the factory one being to small
