Toyota Repair: toyota 2007camry 4 cyl shakes, air intake hose, hose clamps

Question
My 2007 Camry 4 cyl shakes during idling and driving with or without AC on. It shakes less when put in neutral. It has small vibrations during driving at all speed and make me feel uncomfortable.Idling speed seems to be lower than before.

Answer
May be a loose vacuum line or an air leak in the intake.  Check to make sure your hose clamps are tight. Check for any damage on your air intake hose between the MAF sensor and the intake manifold.   Listen for sucking sound in the engine compartment.

Hope this helps.
