Cammer-6, thanks for the reply.
Problem is solved.
I was checking this morning to see if I could detect a difference while reving it cold when I spotted a 4" long, 7/32" vac hose attached to the Throttle Body that was falling apart. When I moved it, the engine started to stall. It was dried out and splitting all along its length.
This hose connects from the Throttle Body (below the throttle plate) which provides a vac signal to the MAP Sensor mounted at the Throttle Body.
I didn't even realize this engine had any vac hose connections since it doesn't have a PCV valve.
Sometimes the simplest things...
I was all set to go out and purchase new Ignition Coils at $40 x 2 and instead a $1 piece of vac hose was all I needed!
Engine running like it should. I'm feeling like a Master Mechanic at the moment!
