MAP Circuit low input.

I "borrowed" a scanner from Schucks, and it spit out the trouble code,
"MAP/Barometric Pressure circuit low input"- P0107. I also got a pending code of "System too lean/Bank too lean (Bank 1)"-P0171.
I was having SERIOUS idleing issues and have changed out an O2 sensor and my IAC valve. My idle has been fixed and works pretty well, but now when I hit the gas, all Hell breaks loose. There's popping, and surging, and general undriveability going on. I have a 1999 S-10 PU with a 2.2. I have put an aftermarket intake, exhaust, and a "Venom" module on it. It has run perfect for over a year! When I turn the module off, the problem still exists. The only reason I changed the IAC is because I pulled it out to clean it off, started monkeying with it, and broke the damn thing!(curiousity killed IAC). Could this be an EGR, Vacuum, PCV, or Emission EVAP issue? Please edumicate me!
LOL, thanks,
