Revs Fluctuating When Idling

For a smoke test you need to go to a garage that has the appropriate gear. To check for a leak yourself you're basically just looking for split pipes, if it's happening while you're idling there is a good chance it will be a vacuum leak. There are quite a few pipes that are common to go.. Check all vacuum lines leaving the throttle body for a place to start
i have checked the pipe work and cant feel/see any split pipes ,but if i take the small pipe off the top of the dv the all rev/ idle returns to normal. help please
Honestly I don't know what it is. Is the DV plumbed in correctly?
The other side of that pipe that you're talking about goes to the n249. Look in the stickies on how to do remove it as that might fix your idle issues
