should i install my front heated 02's with a burned out cat?
 

hey i wanted to tackle the porject of installing my 2 front 02 sensors but my cat is burnt out and something is allways rattleing inside of it. should i install them or can they burn out too becuase the cat is bad??

What does one have to do with the other? The front of sensors monitor the exhaust coming from each bank, WAY before it ever gets to the cat converter.

The only sensor that monitors the cat would be the rear most O2 sensor. The two front sensors are before the Pre-cat (fed-spec) and main cat.

Why not replace both cat and o2 sensor? More than likely, the bad o2 sensor caused the cat to fail. A cat should never fail on its own.

If you want to save money, buy a Universal O2 sensor. It doesn't connect to the factory harness but you splice the wires and connect them to the new O2 sensor (directions are on the box, its very easy). You'll save typically $20+ dollars on one sensor alone doing it this way.

hey...question...im in the process of trying to get my car to pass the california smog check....and well...i found out i need an obd-2, california compliant catalytic converter....anyone know where i can find a decently priced one....so far i checked around here...and the asking price is about 400......online...i just havent been able to find what i need........but if Anyone has any idea...please let me know.
