Hey Im new to the site and somewhat new to toyota's. I have got my first yota which is a 87 4runner. I was curious about the o2 sensors on it and whether it even has them. It does not have a cat. Where exactly are they located so I can see if they have them or not? Is there a site with some pics that may guide me?

Thanks

 

there is somewhere on the net where you can get the factory shop manual (FSM) but i'm not sure where, either google it or hope someone hills you in...as for the o2 sensor there is one, right on the manifold before the downtube, and there should be a cat, its under the truck, right about directly under the driver's seat, if it isn't there it is supposed to have one originally.

also use the search feature provided on the sight, i'm sure u're about to get a lot of sh** from guys telling you to use the search...try that and u'll get a whole lot of info on the topics you want to learn about...

welcome to yotatech!!!

 

Yea I know where the cat is, the guy i bought it off removed it for some odd reason. Thanks for the help though I'll search it

 

welcome to yotatech it should be in front of the cat
