Well to answer my own question, the knock sensor is a 24mm for anyone else who cares. I don't have a spare socket to cut a slot in for the wire, so I just played with tightening and loosening it with a normal wrench, and also put a washer on it as I heard other people had luck with that. Now it's a little better, but it's still there none the less. I found I have a pretty good exhaust leak at the o2/downpipe flange that I thought I fixed months ago, but I guess not. I'm going to fix that, hopefully that will quiet things down a little. I doubt that will fix it, but I feel it's worth a shot, plus it'll quiet the car down a little which is always nice!
