How many o2 sensors does a VR V6 with advance headers use? I've spotted one on the left hand side header, shortly after the pipes merge into one. The car was bought with the headers so i'm not sure if there is one on the right hand side, and there wasn't one spotted from an under bonnet inspection.
And would the number of wires on the sensor matter, as its an aftermarket header setup? I'm thinking of replacing the sensors as fuel econ could be better and the exhaust fumes are quite strong, which i think is an indicator of the car running rich.
