Did you check for vacuum leaks? Cup your hand over the top of the carb as to restrict the air flow and see what happens.... Don't block it off totally (good way to break a ring)

man, the SAME thing happened with my '88 Mustang GT.  i was baffled as to why the idle was really high/erratic and it ran like crap...i had tried most everything, couldn't find a vac. leak...one day i was screwin around and decided to cover the TB to kill it...it sucked in the cardboard (just grabbed a piece to cover the TB) tight to it and KEPT RUNNING!  i cracked up.  then i went and got intake gaskets and all was well after that...

well, if you covered the carb and it still had enough air to keep running, where do you think it's getting it from?  lol, there IS a leak, and a pretty good one if it's enough to keep it running.  it is most likely at the end of the intake where you can't really spray...you need intake gaskets...

Mist down your wires/distributor cap with some water and see if it runs worse.
