it's the second one, so the one downline of the cat.

You only have a single bank of cylinders, a V6 or a V8 would have two.

Good luck getting it out, might be easier dropping the exhaust first.

You seem to be the person I need to ask, as you have already located the manifold sensor, I am pretty new to this and female please dont sigh, I need to be pointed in the direction of the sensor on the manifold have just posted question re above. I have found the cat o2 sensor but unsure were to locate the manifold 02 sensor. Is it easy to remove and do you know exactly what I will need to hand.

Hope you can help!!
