Are there any codes in the computer? Also what does the transmission fluid look like?

There is no fluid in the transmission? You can see leaking fluid? Yes that is normal for the check engine light to be on then turn off when the engine starts?

If there is no fluid in the transmission the transmission wont work correctly and the car wont move. Plus without fluid in the transmission it will be severely damaged. Question is if there are no visual leaks where did the fluid go?

So what happened to the car in February that it had to sit all this time?

Anytime you have code the engine power will be reduced. You have a BARO and EVAP codes is there any symptoms along with the codes?

Here is my take on this whole thing. The p0106 is for your map sensor the p0449 is for the vent control solenoid circuit and the p0452 is for your fuel tank pressure sensor. What do all three have in common they all share the same five volt reference signal or five volt power supply to them. I would be checking the fuses under the hood see if any are blown. Also, those codes will not or should not put the car in reduced performance mode. That happens when there is a fault in the throttle by wire system like a fault in the throttle position sensor gas pedal sensor etc. The traction light might be a clue if it is seeing wheel slippage or thinks that is happening then it would retard the timing and cause a reduced performance feel etc. That would take more than a basic diyer code reader to read ABS or traction control codes. I would first looking into those three codes your getting and see where that takes you. Let me know what you find with the fuses if any are blown.

Nice catch Saturntech9.

Here is a guides and some diagrams (Below) of the fuse layout:

Please let us know what you find. I am interested to see what it is.

I would be really looking in the under-hood fuse box at the 15 amp emissions 1 and emissions 2 fuses.

Without the mass air flow sensor the vehicle's computer will default into a preset or pre programmed operating mode. In this mode the vehicle will output more emissions and your fuel economy will be reduced. Other than that you'll probably not have any issues long-term or short-term. I would not recommend driving up any steep canyons or grades just as a precaution.
Thanks for the question
