Vacum leak

I am new to this and needing some help. I recently replaced the head gaskets in my 2003 Malibu. First time and all seems other than it runs rough at stop lights. The check engine came back on and so I had it read and there is an air flow issue. Nis there anywhere that I can get a schematic for the vacum lines? I have all over and cannot seem to find a loose or broken one. Any other suggestions are most welcome. Thanks

Congratulations! You have had dexcool eat to you head gasket. Be sure and change that coolant out before 100k. Best to use some other type of coolant, I use walmart brand 8 BUX. Anyways, Go here, http://www.justanswer.com/chevy/2khul-96-chevy-monte-carlo-z34-transmission-shifting-erratically.html, This seems to be the setup of my 3.1l, 1998. It should be pretty similiar, but Who knows. There is always a pesky vac line right below the coil pack that gets unplugged on mine, its pretty touch sometimes to get it plugged back in.

Im also sure a haynes or Chilton would have the vac diagram in the back of the book,

What is the state of your EGR gasket. This can cause problems if left off, or defective.
