The flexible pipe that attaches to the throttle body was the worst. Replace any problems with silicone hose.

Please also be very careful with the material used to replace these hoses.

For example, any of the PCV hoses need to be replaced with a special type of hose, otherwise the oil gases will eat away the hose and you'll be left with chunks of rubber in your engine (this is why replacement PCV hoses from toyota are so damn expensive).
