hi guys,

i have a 1982 mercedes 230E and was wondering if my car has an oxygen sensor?

a stupid question i know.

how much would one of these retail for my car, and is it a big job in replacing it?

thanks

 

oxygen sensors are always on the exhaust pipe.... just look from the exhaust port down to the muffler... if there's one it will look like a spark plug with 2 wires...

 

before the cat.
