hi i just got me a 92 ford ranger xlt with the 2.9l v6...and my car has failed aircare..anyways for now i am just doing a tune up on it then i am gonna try again...if that fails i am puting in a new cat....anyways i was wondering where the one of the 02 senors is located...i can see one just before the cat and i changed it already...the guy i baught the 02 sensor from said i should have 2 but i dont see it anywhere....is it in the manifold??

 

i am not sure. but to tune it up try a k&n filter, new plug wires, and plugs before you splurg on a new cat.

 

i have already changed the spark plugs, wires, rotor and cap and put in a k&n filter....my fuel pump and fuel filter have been replaced and i have changed 1 0f 2 supposed 02 sensors....i want to change the other one too only if i could find it......i am gonna run some injector cleaner too and run it for a couple of weeks and try air care again...then if it fails im am replacing the cat....anyways if anyone knows where that 02 sensor is it will be a big help

thanks
