Does anyone know how to fix it up on a Golf GT, 170BHP?
I have a narrow band A/F gauge. I know there are 4 wires (2 white, 1 grey and 1 black) coming out of the upstrem O2 sensor located at the exhaust manifold. I did some research and I think (80% sure) that the grey wire is the signal wire. I only left with the signal wire not connected. I have pictures of the mockup of the engine showing the O2 sensor.
Can anyone confirm this?
