Sounds to me like the first thing you should do is clear all those, and start over. It's pretty hard to troubleshoot a lean condition and a rich condition at the same time, for example; they may have occurred under totally different conditions over who knows how much time.
Easiest way is to disconnect the negative battery wire for a little bit and connect it again. Or if you don't want to lose stations or time on your radio or whatever there is a ecm power line around the battery you can unclip.

what year vehicle is it? what type of fuel system? TBI, Carb, or TPI? that would help to see if u have a MAF or MAP sensor. what if any, symptoms are you having? that would help diagnose the problem.
