Is there a way to clean the O2 sensor?

[alram]

Very low MPG.
Stalls once in a while.
Hard to start a few times.
*** NO RED LIGHT ***
:xeye:
I suspect the O2 sensor because I had those simptoms with my other sl2 saturn
I took it to the dealer and found nothing wrong...they say.
this 2004 VUE has 4 O2 sensors (the dealer told me) and the one in the manifold cost over $100.
So.....can I clean the O2 sensor? and how.
Any sugestions/solutions will be greatly appreciated.

Is it your sensor or your cat converter?

Did it happen suddenly?

Might be bad gas or some dirty injectors. I'd try a couple tanks of some Chevron Techron Concentrate. I'd also consider using some water remover in the gas.

there is not a way to clean them but they are easy to change, if you know which one it is. They really should throw codes if it is an o2.
