I'll update this when I can, and see if I can help better. The intake gasket is the lower one below the manifold, not between the plenum and manifold. I am assuming this is the 3.4 motor?
This may not be the problem, but would be a huge concern if it were mine and if it is the 3.4.
If you changed the vacuum in the motor from the work you did and made it better, a border line intake gasket can get pushed over the edge. I probably jumped the gun. Especially since there are no misfire codes.
