Throwing Codes

Hooked up the car to an ODBC II unit and got these codes.
P2196 = 02 Sen Signal Biased/Stuck Rich B1S1
P0299 = Turbo Charger/Supercharger "A" Underboost
P0101 = Mass or Volume Air Flow Circuit Range/Performance Problem
And Throttle Position (TPS) was stuck at 95%

We then looked at the air filter and saw that the intake into the filter (a micro screen) was completely clogged with leaves and sand. Don't ask me how the sand got there. But it's probably been there since I got the car. Remember I got it used with 10k miles on it.

Cleaned out the micro screen, changed the air filter (which was very dirty) and reset the codes.
Started the car up and things were better but the TPS was still stuck at 95%. So now we are looking into how to fix this 95% Throttle Prosition problem.
