What is it doing? Your question is too vague
if its not under the dash check under the hood
how do you change a brake booster valve to a 1998 Pontiac transport
How do I change the head gaskets on my 1998 ford explorer?
I have a 2000 Pontiac and my was doing the same thing. It turned out to be my heads were warped. You can smell it coming out of your tail pipe if it is your heads.

Carefully.
What engine? and ensure it is a bad gasket, not an intake plentum.
