Help diagnose an engine stall problem that has vexed me for almost 4 years now

[TimQ]

I think I am declaring victory!!! Tracked down a new coil this morning, put her back together and threw some new plugs in for good measure then went for a spin. Probably 45 miles without even a hiccup. Best of all was that she seemed to have some kick back when I hit the gas (yeah, it's only a V6 but still) and didn't have the hesitation like it used to when I floor it. The best test was coming up the final hill by my house. Yesterday I was barely able to get above 40 or so. Today, I shut her down as she creeped past 60.

So, thanks again to all the great ideas...especially all those who pushed me to look more at the ignition and related components.

Now its on to the various oil drips....
