Yet another O2 sensor question.... 200 1990

Hi all,

I know this has been asked before, but where is the chepaest place to get the replacement Bosch O2 sensor. I think I really need one, since my mpg is down from 25.6 to 23.1.

I tried a search and wayy too many links came up.....

TIA!
Raj

25 to 23? If you are comparing to last summer, that is normal winter/summer variation.

Yes, summer to winter....I never thought about that. Is it supposed to vary that much?

Assuming that is you problem, the cheapest one I found was at Auto Zone for $40. It fits a ford mustang - if you don't mind splicing wires. Search this forum for the bosch part number. It works.

There is a simple way to test the sensor on the 700/900 FAQ's. All you need is a digital multimeter.
