Default low boost, low power, SES.....what happened?

i was driving my car today, and i notice my SES light would come on when i started it, go off in like a minute or two, come on for a minute etc etc, randomly as i drove. never stayed on or off for too long

it seemed to drive just fine untill i got on it and noticed that its only making about 2-3 lbs of boost, and its ALOT slower. it feels about as powerful as id expect a 93 non supercharged 3800 to be

also, i smelt something, like unburned gas when i parked it, but that may be because i kept flooring it wondering why id only pull 2lbs of boost (for like a minute)
stock 93 ssei

If you look closely, two holes will be labeled A and B. Put a paper clip between those two.

Your IAT is disconnected. Your BCS is either disconnected or bad.

After addressing these two issues, disconnect the battery for 30 minutes to clear the codes, then drive for a week and check again.
