Default Trouble codes po106,171 and 174

About 2 days ago my engine check light came on, so I went to autozone so they could see what codes it's showing. It said po106 which means the MAP sensor isn't performing right and codes po171 and po174 which means both the left on right banks are running lean. Could my injectors be clogged up or something? And I don't know what to do about the MAP sensor, please help.

I would say the bad MAP might cause your lean condition, I would start there.

I'd venture out and guess that your intake gaskets are leaking and causing the codes....try spraying some carb cleaner type chemical around the base of the intake while its idling, if you notice a stumble you've found the problem, but keep in mind that doesnt always find the leak on the back-side of the gasket. Without seeing the actual freeze-frame failure data intake gaskets would be my first guess.
