odb2 code readings of p0101 and p0068

I have a 2004 Pontiac Grand Prix GTP Comp G Supercharged and when I try to start my car it will start but when i go to tap the gas pedal the rpm's won't go up and will stay where they are then I get a reading on the computer on center of dash saying reduced engine power and then it shuts off. I hooked up a ODB2 scan tool and got a code of P0068 (Manifold Absolute Pressure/ Mass Air Flow-Throttle position-Confirmed) and then received another P0068 with (Manifold Absolute Pressure/Mass Air Flow-Throttle Position-Pending). The Third code I got was P0101 (Massm or Volume Air Flow A Circuit Range-Pending). Can you please help me with what to do. A friend told me I could take off the MAF and spray CRC quick dry electric cleaner in there and it will work, will it? What do you think I should do about these issues?? PLease Help ASAP!!!
