Stalling Supra

Since my post I have been able to read the codes. I am getting a code 52 for the knock sensor. Have gone over some of the wire harness looks ok so far. I know the knock sensor retards the timing but can it cause such a dramatic drivibility problem? The car actually starts to buck @ 2-2500 rpms, until you let off the gas. If you punch it and it gets past 3k, all is good. Additionally, after resetting the ecu, it was doing this with no check engine light on. This thing is driving me nuts. Off the subject, I have one other question, one day I shut the car off and when I started it again my speedo didn't work. Everything else on dash is fine, just the speedo. Any body seen this before?
