I built a pressure tester from information gathered from the search, yes I used it before asking. However, I found nothing that answered my question.

Here is the diagram, part in question is #22.

I found the leak in my system at this part. My question is if there is supposed to be a gasket between the metal plate on the bottom and the plastic piece. Hopefully you can see my red arrow pointing to the area I'm referring to. when I took it apart, there was no gasket. In fact, when I put the 2 pieces together, they didn't sit flush, the metal piece kind of rocked back and forth. This is the area that my leak is coming from.

I just went stage 3 2 weeks ago, and I'm wondering if this wasn't mistakingly left off.

My car was running very smooth until a couple days ago, when it would jerk at WOT.

Thanks for helping.

Don't think so, but there is supposed to be a clamp where the boot meets the bottom metal portion.

EDIT: Make sure that there is an o-ring around the plastic sensor piece and that it is not damaged.

just like dave said, check for the oring and you are missing the clamp on the tb boot

need to order the o ring, what is this part called?

daves4izzle::ASP 3-

part. However, the o-ring for the intake air temperature sensor is just about the same size and it's part # is 095 323 969.

To everyone else, it's the intake pressure sensor or MAP sensor.
