I figured out my problem. Turns out I've got 2 issues, MAP error and VSS error. I'll talk about the MAP error here and close the thread, because I've gotten the MAP error to go away, and concentrate on the VSS error on my other threat.

The previous owner of my suburban disconnected the charcoal canister, so the tube to where the canister used to be is just sitting there. I just noticed that somebody (it must've been a mechanic, because it wasn't me) plugged the end of that cable with a bolt. I guess they thought it would cause a vacuum problem to have it not plugged? Anyway, when I took the bolt out, the MAP error went away.

Anyone have any idea why?
