fuel pressure regulator?
91 FSB 5.0
My truck is running really rich, almost feels like it's flooding sometimes.
Also it seems like my accelaration is messed up. Its either slow or fast if that makes any since.
Any suggestions?

Sounds like the TPS, but you can pull the codes to find out, or you can test the TPS itself with a voltmeter. Instructions can be found here with a search and I believe they're in the haynes manual as well.
If you're worried about fuel pressure, put a gauge on it. They're about $30 and you can find them at parts store and sears.

I have no expertise in this but I remember several threads suggesting to check the fuel pressure regulator. It's the thing on the fuel rail near the firewall. Pull the vacuum hose off it and if gas is in the hose it is bad if my memory is correct. To search see "Forums" up above then "Search"
