Throttle body question........

[BoostedBird]

I was doing the VFAQ leak test and I can heard air leaking near the throttle body. When I looked closer, I saw that on top of the throttle body, there are 3 fittings were hoses could come in. Labeled P E A. They appear to have a ball bearing looking fitting in each of the tops of them. Well at least the E and A fitting do. My P fitting is completely empty. No hose coming in or ball bearing "block" on top. Is this right? Am I missing a vacuum line? Could this be the cause of my not being able to boost past 9 PSI? Any help is appreciated.

ANY help is appreciated. Can another 2Ger look at their throttle body and see if they have the same setup?

Your not missing anything, my "p" is also empty and does not have a vac line.

i think if you didnt have the hose on it wouldnt run good at all were a leak would prob cause you to lose some boost, not sure though, but also under my intake mani theres 4 outlets, only 2 are used thouhg

Thanks for the replies. I did a pressure check last night and sprayed soapy water on there and nothing so I figured I was OK. But I was getting a leak some where by the throttle body. Sprayed all around it and couldn't find it. I heard something about rubber seals on the throttle linkage or something. Anyone know any leak possibilities around there or heard of this?

is it the intake elbow to tb gasket? tb to intake mani gasket?

also check your vaccum caps for cracking or maybe if they are coming off.

I would check to see if the TB is actually tight on the intake mani.

Don't know if it is between the TB and the manifold or the elbow and the TB. I sprayed everywhere. Didn't see any bubbles. Seems like it is from the back of the TB. Ordering new seals just in case. Will see what that does.
