Paul, Thanks for the info.
I still believe that the intake had a slight vacuum leak from the factory. Think of this for a second: The engine idle RPM's were fine prior to removing the intake plenum. (Which was being removed to replace a faulty injector.) I noticed the intake gasket to look like it was not sealing properly and replaced the gasket. Then without adjusting anything I re-installed the plenum. The idle RPM's were now so low that the engine couldn't (and wouldn't) remain running. To me, this confirms that there was an intake leak prior to removing the plenum. Until I was troubleshooting the injector the engine had never seen a wrench. So, I know everything is factory original. Slightly opening the butterfly fixed the idle issue. And it now drives perfectly fine. We will be taking it on a trip this weekend where it will have almost (2) tanks of fuel use and I will be checking the mileage.

Just FYI, that throttle plate stop screw shouldn't be adjusted. Desired idle speed is achieved by actuation of the idle air control valve, which is probably sticking similar to how the butterfly is.
