Intake Problems
I just purchased some Fel-pro Intake Manifold Gaskets MS93317for my 92 Chevy Camaro. I was wondering if I should have cut out the rear coolant passages on the gaskets. I wasn't sure, so I installed them without taking them out. Now it is running awful, it cannot hold an idle and a hissing noise is heard from it. Also, I only get heat out of the defrost vents. What happened? Is it out of time; Are there more gaskets I should have replaced? Also the vacuum tee running to the fuel pump may be not hooked correctly..... Any advice would be appreciated....... Does any know Anyone in my Area that can fix this problem? Money isn't too much of a problem..

Re: Intake Problems
It sounds like you have a vacuum leak, there is no vacuum going to your fuel pump and the reason why the air comes out at the windshield is because the vacuum is what controls the damper, so check your vacuum lines by squirting them with carb cleaner with the engine running and when the engine changes idle, thats where your leak is.

Re: Intake Problems
You must be thinking of the evap and that diagram is on your hood. The damper is what controls where the air comes out.
