I was getting some random high knock numbers for a while. I fixed all sorts of stuff, still had random knock over 10 degrees. Replaced the knock sensor and it's suddenly cured. I never thought it would fix it but it was about the only sensor that I hadn't replaced so I said what the heck. Just an idea anyway. If you do replace it, it's important that it's torqued to 14 ft lbs.
 
If it's over-torqued it will be too sensitive. 14 ft lbs isn't much. Definitely go back and torque it properly.
 
IAC is low, should be around 25. BLM is a little low (rich) but within spec. Should be 128 +/- 10. O2's at wot are ok but could be a little rich also. What is your fuel pressure set at with the vacuum line off?
