Help please 2008 HHR ss no power
Went to work and car drove and started fine. Got off work and car took 2 times to start. Had to make a stop , came out and took 2 more time to start and started a little hard. The car cut off as I was backing out , driving home car had no power. Stopped at the parts store to check the codes and the codes were p0011 and p0016 , I changed the camshaft sensor, disconnected the battery and changed the intake control solenoid. Car just turns over and won't start .
