If you have an 01 Job 1 then you do not have the elbo that most of us refer to. You will need to check for a vacuum leak the old fashioned way by using some sort of spray while the engine is running. Most use Carb Cleaner.
If you have a job 2 then look in my Library and you will find a file that has pictures of the location of the elbow that goes bad....
(I am on my PDA or I would post the pics for you, sorry about that).
