noticed lack of power so ran on scope came up as misfiring on the way home temp gauge began to climb until just got to below the red I imediatly shut it down and let cool then I changed plugs and wires and refilled the radiator with dex-cool, I started it up and it ran well for a few minutes and then it started to run rough and it stalled then I noticed water coming from the air cleaner. is the intake gasket gone or is there something else to check and if it is the gasket how big a job is it?

The plastic upper intake manifold has burned thru at the EGR pipe. If you remove the throttle body (three screws) you'll be able to see the damage.

replacement manifold sold thru NAPA, CarQuest and other retailers is designed for extra clearance between the manifold and EGR pipe and is probably much less money to purchase than an OEM one.
