I am taking my car to the dyno in a few weeks and need to verify the O2 sensors easily come off. Just want to make sure they don't have any problems so I can get my A/F ratio checked.

First question I have is how many O2 sensors and the location of them. Is it just 2 sensors, 1 on each exhaust manifold? For those that have removed them, how easily did they come off? Did you use any lock lubricant or a special O2 socket?

Thanks for any feedback.

 

There are 3, 1 in each cat and also 1 above the cat on the right side of the midpipe. I personally used a special socket to take them off when i swapped midpipes because the very top one would be incredibly tought to get to without imo.

Edit: Smarter men than me realized there is an extra one [img]style_emoticons/<#EMO_DIR#>/icon_mrgreen.gif[/img]

 

3 that I've found so far, all behind the manifold. 2 on the right side, one on the left. Easy to remove with the right size wrench.

 

There are four, two on each side. Drivers side has one in the manifold and one in the h-pipe. Pass side has two in the h-pipe.

 

Yes there are four.
