O2 Sensor... do we need it for the PFC??
I haven't changed my O2 sensor ever since I got my car... however I rememeber someone said that the PFC doesn't rely on the O2 sensor.... There is a function where you can turn it on or off but when I did... it seemed that that car started bogging so I turned it off....
Should I still get a new O2 sensor???? My Gas milage isn't that bad and I'm running pretty stoich for air/fuel.....
What do you guys do?
thanks

Most guys on the forum turn the O2 stuff off. However, most guys on the forum are heavily modified. The fuel maps can be tuned to get better fuel mileage than O2 feedback would provide but this takes a while to tune. You will probabely get better fuel mileage with O2 feedback on. Your O2 sensor is likely fine as they usually last a long time but may get off a bit over time. I would leave it on unless it's causing problems.
