Vacuum Leak
 

I am experiencing a vacuum leak from my engine and think my problem might be related to the Int-x uninstall. During the installation process for the Int-x, there is a step to hook up the supplied hose to the nipple on the manifold (underneath portion, right hand side above oil dip stick) to assist with measuring manifold vacuum pressure. When I uninstalled the Int-x, I didnt plug this hole and think that my issues are because of this.

Does anyone know if this hole should be plugged? Mine currently is not and at idle I can feel the vacuum coming from this area if I place my finger on it.

Thankx for the comments everyone!

Absolutely.....
 

MUST be plugged.

That large of a vacuum leak will affect both the fuel trim settings, cause rough idle, and suck in debris!

Why would you leave it open?

Cap it, if you don't have a cap, use an inch of tubing with a stubby screw in the other end. Then reset the computer to get rid of the f@ked up settings.

Why not hook up the vacuum line that is supposed to be there from the VFAD?

RB products are installed on my car..

Thankx for the input guys.. I'll plug the hole.. (Novice)..... Obviously :)

I had the Int-X installed on my car and could not remember whether or not this needed to be plugged.. I have been running with it like that actually for the past month and have only been experiencing issues just recently.

I did happen to look at my LTFT value and it said 20%.. I knew there was something wrong at that point on a N/A car...

Should have known better but I just did not know.

Thankx again..

the rb intake should have come with a red vacuum nipple plug.

Ohhhh yes........ Now I remember.................................. :) Thankx for jogging my memory.

Umm....... red nipples!
