2: P0507 idle air controle systems revolutions
3: P2103 throttle actuator

If the battery is good you probably need a throttle plate/sensor assembly

 

I have a 2007 g35x. Same thing happened to me today. Waiting for tow truck now. Unsure if codes are thrown. Can't wait to hear what garage has to say.

 

You guys need to replace the throttle body.

 

I would try to reset the TB before you replace it. Search and you will find the procedure.

 

yea my battery is good, reset TB... this is what i found;

Throttle Valve Closed Position Learning

1. Make sure that accelerator pedal is fully released.
2. Turn ignition switch is ?ON?.
3. Turn ignition switch is ?OFF? wait at least 10 seconds.
Make sure that the throttle valve moves during above 10 seconds by confirming the operating sound.
