Still having engine problems 700 1989

This is an update to a previous problem. Occasionally when I'm accelerating, my engine will lurch (like a sudden drop into a low gear) and do one of two things: 1. Immediately die and sometimes have some problems restarting 2. Re-engage and pick up speed, and the tachometer needle bounces for a few seconds before stabilizing. I got my clutch replaced last summer, so I thought that might be a culprit. I also had three OBD codes (232,131,214) until I replaced the crank sensor this past weekend. Now I have codes 232,131, and 133. I haven't been able to clear the fault codes on port 2, so I think 131 may just still be in memory, but why would I be getting 133 after replacing the crank sensor? If anything, my engine idles low, not high. And what would be causing my lambda control to be off?
