I changed the manifold gaskets on my 2000 Malibu 3.1 and it is running just fine!Get a haynes manual from the parts place and the instructions are in it. The book at advanced auto is about 20.00.
if its a v6 and you take your time. it takes about 6-8 hours, depending on how fast you work !
Was an intake manifold gasket for me.

if its a 3.1, the possibility is the intake manifold gasket!!
I have a 2002 Pontiac Gramd Am and its in the shop right now getting the Intake Manifold Gasket fixed on it! Its about $2000 with labor costs and everything! Rediculous! Its supposidly VERY common in these vehicles....They should do a re-call!
To replace the Suburban manifold gaskets, unhook everything on the manifold, from fuel lines to vacuum hoses. The manifold needs to be unbolted then removed. Clean the old gasket material, then install with a new gasket. Make sure to use factory specs when torqueing down the bolts.
Head gasket repair on a 2002 PT Cruiser requires extensive time, knowledge and tools. The intake manifold, cam shafts, and cylinder heads must be removed.
They (2ea.)are in the intake. The intake manifold will need to be removed to get to them. The wire harness and intake manifold gasket should both be replaced when reassembling.
I had this problem and the manfold gasket was leaking I am aware of sensor issues with this but I has to replace the manifold gasket problem solved.
They have problems with yhe intake manifold gaskets. Felpro has a improved set that do not leak.

There are a few causes: Damaged or disconnected hoses (or component) from intake manifold. Worn out intake manifold gasket. Improper replacement of a part. Cracked or damaged intake manifold.
