Had the day off so I decided to tackle getting the downstream o2 sensor spacer out of the midpipe.
Had to unbolt the mid-pipe from the header, unbolt the mid-pipe supporting bracket and slip off the third farthest-back exhaust hanger to get enough room to twist the 90* spacer out without it hitting the underside of the car
Then the o2 sensor seemed to have fused itself into the spacer, so I hit it with some penetrating oil
While it set for a few minutes I decided to remove the leftover bracket from removing the AC that supports the alternator cable, a few zip ties cleaned that up
Then I got the sensor out
Re-assembled everything and realized that with the sensor coming out of the mid-pipe normally, there isnt enough length to plug the sensor back in, so up top I had to get some more room from the harness.
This is how it looks stock
and how I had to tweak it
Then I ventured out into the "hurricane" and drove about 30 miles, no CEL so far. Hope that solves it
