Hi guyz,

I'm Going to change my O2 sensors on my Eunos 30x (Mx3)
At first I thought there is only one O2 sensor for the engine but after reading some of the posts in this site Now I believe there are at least 2. So correct me if I am wrong ...

There are 2 O2 sensors on the 1.8 V6 engine and I found one of them in the front which I probably can get to from the bottom. Where the hell is the second one ?? and are there only 2 sensors or more than that ??
help me out.
Thanks guyz
