Question: check engine light

I have a 2006 Pontiac G6 GT. The Check Engine light is on and I can't figure out what is causing it. I've replaced the pre cat O2 sensor, the mass air flow sensor, the connectors to the mass air flow sensor, and the air filter. The car is shifting hard and the light does not go out. The code is a P102 and a P030. Says that the circuit has low current. Do you know what else it could be?

You could have a vacuum leak. Or the air pipe going from the MAF sensor to throttle body. Or you could have a broken wire causing the code. One last thing just because the MAF sensor is new does not mean it's good.
