Ok So i have 98 A4 and lately when i start it it has a rough idle and acts like it wants to shut off. This morning it did shut off a couple of times before getting out the drive way. When accelerating it revs way higher than usual and the other day it went into limp mode. My check engine light isnt on and I have no clue what it is. Was told it could be a vacuum leak. IF u have an idea please help =]
Thanks!
