I'd recommend starting a fresh thread, this is informational only.Maddogmil said:HOW BOUT THE INFO ON CAUSES OF P2196 PLEASE! rumor has it that o2 dont fail rich.
In your case, I'd examine wiring to/from the O2 sensor to verify it isn't in some way damaged. Once that is verified good, you have to assume that either the sensor is non-functional, or it is actually reading rich due to a tuning or mixture problem elsewhere.
I'd recommend working with somebody experienced to examine the car.
