my 96 accord lx coupe needs new 02 sensors. Can anyone help and tell me where they are located and where i can buy new ones. Also which ones are the best to put in?

 

Nippon Denso is the original manufacturer. That is the best / most compatible brand.
There should be a primary sensor located at the bottom of the exhaust manifold, then follow the exhaust pipe back to the Catalytic Converter and you'll find the secondary/monitor sensor.
Have you had this problem diagnosed? It Seems strange that both sensors would be bad at the same time.

 

Two sites I have ordered Denso O2 sensors from at good prices:

oxygensensors.com

sparkplugs.com
