i had a similar problem some years back with my 2000 Blzaer. replaced the same items and even went as far as reploacing the distributor assy. turns out that i was getting moisture inside the cap from a crack in it. check ur distributor for cracks or make sure the seal is good on the cap/distributor

When you changed the wires, did you also change the coil to distributor wire? The routing of this wire takes it against a metal bracket, and can damage the insulation causing a misfire.

Here's the thing. Since it has become MUCH colder here, the problem has all but vanished. Ideas?
I chalk it up to being a self healing Chevy, but I'm sure there is a much better, mechanical or electrical explanation.
I hope this will help pinpoint whatever was making it act like it had "pondwater" for fuel.
Oh~ I also quit using WalMart's fuel. Related?
I only bring this up, because I used to drive 60 miles per day, and that is where I would get my gas. (plain unleaded) Then when I got my new job here in town, it sat for months. As I would only drive it now and then, it would have taken a long time to remove the deposits that cheap fuel would leave behind.
 
Just grasping at straws here...
