Finished replacing intake manifold gasket. Car runs SO much smoother now. Wasn't too hard of a job since the old gasket was very brittle and came right out. I like the way the holes fit up to the bolts on the new gasket so no worry trying to hold the gasket in place.

The tell-tale that I needed the gasket was this: I sprayed throttle body cleaner around the intake seating surface while the engine was running and the rough idle smoothed out. Car runs great now. Thanks for all the help.
