Ok, so getting the rear O2 out of the block is a piece of cake it wasn't difficult. I used the tools mentioned and just backed it out. Super easy. Then I removed the bolts for the guard and moved it up so I could get the knock sensor out. Well as I'm sure you are aware the knock sensor is slightly larger than the area between the engine block and trans. I played Tetris for about 2 hours trying to get the thing out. I then realized that the bracket that connects between the engine and trans (pass side) only had 3-15mm bolts and seemed easy enough to remove. The first 2 bolts are pretty easy and came right out. The 3rd was a bear. Gearwrenches don't even have enough swing. I was able to use a stubby wrench to remove it.
Now the bracket won't come out. It acts like there is another bolt, but I don't see anything. If I can get this bracket out the sensor will slide right out. What am I missing?
