Running it without the MAF is eventually going to cause it to run worse. In some cases, it won't start without it.
As far as the spudder, at that mileage, the injectors, maf. Should be fine and not need cleaning. I need you to also realize that it is still under emissions warranty for 5 years or 5K miles. That covers most of the sensors, fuel cap, any thing with the EVAP system. Also, since you only have 13K on it and it's just out of warranty, I would contact the regional rep for Pontiac and ask for help. Let them know how well you have taken care of it and you feel that it is an emissions problem relating to sensor that the dealer can't find. And at such low mileage, you shouldn't be having any trouble.
LEt me know what you think. Please realize that without an engine code, it becomes a guessing game. I could tell you several things it could be, but again, they would be guesses at this point unless the check engine light come on.
Let me know if you have other questions.
