Does it make any sence to have the O2 sensor, ECU and any other critical sensor gounds all ground at the same point?  Or are you risking a ground loop by doing this?

With the problems with the ECU and O2 sencor and grounds, I was wondering if making an alternate ground path that both are tied to would be a good idea or not?

In my Van, the DPO crimped on an extra ground which is simply screwed into the sheet metal under the seat.
