Hello All,


Noob here.. I have a 1998 C-280. trying to find out where is all the O2 sensors (i.e., how many banks) and how many wires the sensors have. I was told that they have O2 sensors in front of the cat. and behind the cat., also they are on both side of the engine. If someone can point me to the right directions, and where I can buy the Sensors. I am trying to replace them myself. Thanks in advance for the help..
