you need to have someone look for a vacuum leak...
Replyortizcristobal, October 31, 2012, 18:14Rookie
how many vaccuum lines could be involved?
or wich is the most common
Replyyour.mechanic, October 31, 2012, 20:55Master
a few vacuum lines COULD be involved...but it usually is not as easy as a vacuum line...most likely it is some gasket somewhere in the intake portion of the engine.

Gaskets sound expensive

Gaskets themselves are not expensive....what may be expensive is getting them to their place!
