Read the post and you will find that no ONE cylinder has been identified as 
lame.  All the plugs were black indicating all four cylinders were running 
excessively rich at the start of the troubleshooting session.  He then pulls 
the injector plugs one at a time and notes a change for TWO of the cylinders. 
 Now, if you want to bet that two injectors or two plug wires became hinky at 
the same time and then you are going to identify which it is by swapping 
things around, I'll give you some good odds!  I have attached the grist of 
the original posting to refresh your memory:

<< 1) At first engine wouldn’t start.  Flooding?  Pulled the plugs - they

are BLACK.  Changed the plugs, rotor & cap (overdue anyway)

2) Engine starts.  Runs rough.  Exhaust smells like fuel.

3) Plenty of exhaust pressure at the tailpipe.  Does this rule out a

plugged cat?

4) unplugged the O2 sensor - no change - still rich and rough

5) Maybe a bad injector?  Decided I'd unplug injector wires one at a

time to see what would happen:

Unplug wires at cylinder #3 - idles much rougher, plug back in

Unplug wires at cylinder #4 - no change to idle, plug back in

Unplug wires at cylinder #1 - idles much rougher, plug back in

Unplug wires at cylinder #2 - no change to idle, plug back in

Does this mean that injectors #2 & #4 have failed???>>
