i need some help, i been replacing parts for about 4 years now and i changed the oxegen sensor out about three years ago and pulled it recently and it was all black naturally and was wondering being cali emissions and carb while running rich for about 2 out of the 3 years it has been in, would it be worth changing? anyone notice a change in mileage? and what about brands? have 30,000 miles on current oxy sensor, bosch brand. how many miles have you all changed your sensor out at? please help!!!!

I don`t know if changing the oxy sensor will make any difference, but your better off staying with the stock oxy sensor. The bosch sensors arn`t the best to use on our trucks, it seems that alot of people have problems with them not working right. (as i said, thats what ive read, i have no personal experience using them).

When I was working on my 85 22re O2 sensor I read on a web page somewhere that you can put the O2 sensor in a vise(holder) and use a propane torch to test the voltage, it must be 0.1-0.9 volts DC.
