Hmmm. I assumed that a malfunction on an O2 sensor would drive the mixture control for that cylinder bank to full rich trim, right? (lean is bad news, and with the defective O2 circuit, it has no way to monitor combustion efficiency. Seems like the safe position would be full rich).
Agree that driveability remains unchanged, but mpg decreases, right? May be of more concern to the owner than just increased emmisions, especially with the "outta there!" gas prices we've been seeing lately!
Does the 96 have 4 sensors? I know the 95's have 2, and I thought someone said the 4 sensors started in 98 model year (?)
Maybe all the above is just BS. I'm still learning about all this myself. :rolleyes:
FWIW
