Is an O2 sensor and a lambda sensor the same thing? Where abouts is it on the car? I have a yellow engine warning light which keeps coming on and off which is emissions. Been told that its the O2 sensor or the cat.

On an E30 it's in the exhaust down-pipe.

330. Sheeeet! Might just leave it for now then as it wont do any damage. Looked on ecp for a cat and they were £900 odd.
