173-HEGOsensor fault/rich
212-Loss of ignition diagnostic moniter signal/SPOUT circuit grounded.


Does the first 2 mean I have a bad sensor??? Or what? Or is it because of the Long Tubes(If so I've had them in there for a while without a SEL). What the hell is the 3rd one??!! I've had that one in there since I bought the car...... Thanks guys

I think you're on the right track with the O2 sensor - it's related to LT's or the tune (the LT/tune guys will know).

Code 212 can mean you ran without the Spout connector installed or that there is an issue in the SPOUT wiring. You'd probably see an issue when you datalog (you'd run at base - SPOUT OUT - timing).

Good luck.
