yes you do have a MAP sensor
it located on the passenger side of your engine bay below the cowl
it looks like a little rectangular pill box with a vacuum line going into it
if anything goes wrong with it, it has to be replaced, its not serviceable
i'm not sure on a price but:
their not much
go to www.napaonline.com to get a ballpark price
what the MAP sensor does it messure the pressure (actually pressure differential) change inside the intake manifold
because as engine load changes, so does the vacuum inside the engine

You can probably see if it's output is on par with a multimeter...but how to do that is beyond me...I'm not good with electronics. Bought my digital multimeter and I still havent found a use for it yet..this stuff's over my head.

Yeah, the GM Service Manual ( http://www.helminc.com ) would tell you how to measure the map with a meter.
