I just ran the test on my 93 3.9 auto truck and came up with the following codes
12
52
34

I know one of them is the oxygen sensor reading too rich, and another is a speed vacuum or something to that nature. Anyone have any insight on how to fix it?

52** System rich L-Idle
Adap at lean limit
or rich R-Idle
Adap at lean limit O2 sensor signal indicates rich air/fuel ratio during engine operation. The computer ran the mixture to the lean limit of programming, but the O2 sensor still indicated a rich condition. L or R indicate left or right side O2 sensor. Faulty ignition components, high or low fuel pressure, or leaking injectors can set this fault.
Possible leaking injector/s = check fuel pressure
engine off - should hold -=- even overnight..
This situation may be affecting that speed sensor
