Hey guys,

While my Z is in the garage for a clutch replacement, i decided to delete the prvr and the AIV.
While deleting the AIV i noticed that the vacuum line going through the passenger's side fender wall was disconnected.
Anyway i deleted the AIV and the PRVR, but i just wanted to know what is the effect that this unplugged AIV vacuum line would have caused.
thanks.

 

Well if the vacuum line was loose, your AIV system wasn't active, and you had a vacuum leak that was cannibalizing horsepower.

Cap it.

 

It was CUT by the dumbass previous owner!

i removed the whole system and its associated vacuum lines
