OK.....

As the description stated, I had the car running at night with the lights on, AC on and started rolling the windows down. The engine started to stall out. It would drop down about 200 rpm, then go back up to normal...then drop a little more...and go back to normal then stall.

The greater the electrical load the more evident the problem and the faster it stalled. I can get it to recover be giving it more accelerator.

My best guess.....

The driver side door has been taken apart at some time in the past, probably an accident as the car has been repainted. Might there be a short involving the power window motor that is involved in causing this stalling issue? The drivers side window being lowered really get's the stall cooking.

Thanks for your input.

Mary- sounds like you're on the right track. Power windows shouldn't draw enough juice to drop RPMs by 200. My RPMs drop by about 50 when hitting the window switch at idle (~600 RPM normal idle, 1992 5.0 TBI engine, all stock).
