O2 sensors are usually on the exhaust manifold. Actually on the '96 Galant, one is in the header pipe (the pipe running below the engine between the manifold and the catalytic converter) and the other is in the catalytic converter.
Both before and after.
On the downpipe before the catalytic converter.

there should be 2 oxygen sensors, one easily seen just coming off exhaust part of engine and the second one just past catalytic converter.
you have or should have two oxygen sensors on exhuast pipe. one before catalytic converter and one after it.depending on which engine you have you usually can see the one closest to engine from under hood.second one " SAFELY" jack up car and look just past catylitci converter should see it easily.
It's on the exhaust manifold right under your hood, at least it is in my 2000 Galant 2.4 L.
where is bank1 sensor2 on the 1999 Mitsubishi montery sport 3.5
It should be equipped with both.
The oxygen sensors are in the exhaust one either side of the catalytic converter(s).
towards the middle of thecar installed into the exhaust pipe
1995 2.4l galant has two oxygen sensors. one before and one after catalytic converter. Get some WD-40 and spray were they are screwed into exhaust system ,then disconnect oxygen sensors and use good size wrench to loosen. When you put back in or purchaes new ones make sure you coat threads with antiseize compound before installing,unless you never ever want to get them ou again.OH the second sensor is very easy to disconnect if you take out front drivers seat., 4 bolts and its out.
Depends on the year of the car. If the 3000gt is a 91-93 model then the oxygen sensor should be right before the catalytic converter sticking off of the exhaust pipe. If it is a 94-99 model then there will be one before the catalytic converter and one right after it as well.
