I did read the link as suggest by Greg.

I checked the resistance of the coils I removed and here is what I got:
0.6/5.7K
0.6/5.69K
0.7/5.88K
0.6/5.62K

So, I don't think coils were my problem to begin with. However, I could be wrong and would be glad to hear it if I'm thinking about this the wrong way.

Maybe today I'll get time to pull the plenum back off and ohm out the plug wires and new coils.

I have noticed something else that might be relevant. When I'm sitting and I go from idle to W.O.T., I can hear a bit of a sucking noise for maybe 1-2 seconds. Could I have a vacuum leak or is a sucking noise from the throttle body normal?
