Hey Gents, <and Ladies>,
Happy Spring and Happy Boostin.....:->
Got one quick question for all you "wiseguys"?
The DSMlink has been showning my o2 readings as just "disappearing" about 50% of the time, and I'm getting VERY bad mileage, <like 12 mpg> so I'm thinking of replacing the o2 sensors.
The question being, with a "catless" system, should I even bother with replacing the back sensor, as it throws CELS anyway, since going catless?
Is the back o2 sensor an important part of the system, even after going catless or not?
Many Thanks in advance!
