do you have your map sensors hooked up properly? One should be open to the air and the other gets vacuum. If you look at map on the pcm, you should see about 20 hg of vacuum at idle. If your baro gauge reads that..it'll goof things up.
I love diagnostic aids that support my first ideas. =0)

Keep in mind this is for a 98 Bonne, but it gives us a description of how/what might be possible.

I'd think that either one or both are peeved. So the question is which sensor is unhappy? You could unplug maf and drive. So then maybe it's only the map/baro sensors. I'd start looking in that area.
