I'm putting this hear because the trouble first noticed was, apparently, with the VSS. Anyway, the speedometer stopped working while similtaniously the transmission stopped shifting, so after some research I concluded the VSS was the source, so I replaced it and everything was working good, for a few hours, and is now doing as before. I noticed I was tripping a code so I pulled it with the short method and to my surprise I'm coming up with 16-?, 24-VSS, 35-IAC Error ,45-Rich exhaust , 54- Low voltage to fuel pump, 72-? . It makes me wonder if I have a bad ground somewhere but wouldnt I be blowing fuses? Which I'm not, so what the hecks going on? Thanks for any suggestions.

FYI, I have a 1993 Astro RWD

definitely start checking grounds. A bad ground won't blow fuses, but it WILL make everything act crazy. I'd start at the battery, then the engine block, and go from there.Check your battery voltage as well, running and engine off.Bad batteries have been known to cause things to go haywire too.

X2 on checking the battery first.
