I am getting horrible mpg.

So, when I had my OBX header on, I also installed a new o2 sensor for the manifold (Bosch, yes I now know not the best).
Anyways, when I put the stock manifold back on, the OEM o2 sensor was already in.

So, today we are going to replace it w/ the Bosch one, and since it is already out, is there a way to clean it?
Hopefully it will help MPG since the Bosch one wasnt used that long. The OEM one is still from the factory.


I added a once in 9,999 mile fuel system cleaner, and a small bottle of another fuel cleaner when I put a couple galloons in, so we'll see what all happens!

 

Stick it in a propane torch flame for a few seconds to burn off tha junk and the wipe the carbon off. Chemicals have a tendency to foul the sensor.

 

Alright, might have to try it.
All the additives said O2 sensor safe.
Gonna put it in now!
Thanks!

 

You removed your OBX headers?

 

Bosch is the inventor of the modern fuel injection system.
Why wouldn't their O2 sensors be acceptable?

 

Got tired of the gaskets going out, and thought it was the cause of my bad mpg.
Guess not...ugh.

Aw well.

 

In general, most people do not like Bosch on foreign vehicles.
Their spark plugs for our cars tend to burn out coils and other problems for our cars.
