2G - Rear O2 Sensor CEL "Fix"

[EvolvedDSM]

For my fellow OBD-II owners who are tired of staring at that CEL when you pop on a test pipe for those "off road only" events ;) Swing by your neighborhood auto store and look for the HELP! products. Pick up item #42009 (two 18mm spark plug non-foul adapters). You'll notice that the hole in the end is a little too small for your sensor to fit through. Drill one of them out to a little more than a 1/2" (go in baby steps as you'll want to keep the hole centered). Put the unaltered one on the bung attached to the pipe, then put the englarged one on and, finally, the sensor itself. (Hint: keep the test pipe disconnected and allow the rear section of exhaust to hang down to allow more room to work with.)
