-- [ From: Huw Powell * EMC.Ver #3.1a ] -- >I am trying to replace the oxygen sensor on my 874kcsq but can not find where it is located. Could someone please help? I know 8 billion people will probably reply, but it should be mounted into the front of the cat or the pipe right ahead of it. Follow the wires... if you can!
