Hi,
I checked out the manual and it says the o2 sensor is in the exhaust manifold somewhere, but I haven't found it. Can anyone tell me where it is?

Also, my fuel gauge doesn't work... any ideas?

 

The O2 sensor should be right in front of your engine sticking up out of the exhaust manifold and one more right behind the cat converter. The fuel guage could be a few things, bad guage, bad sending unit etc. That would require some research.

 

I did manage to find the one on the manifold, but the one after the cat is proving difficult. Is there any kind of schematic available? The manual I downloaded only shows one O2 sensor.
