When you mentioned in your first post "falls flat on her face" did you mean it stalls? If that's the case it almost sounds to me like if you replaced the ignition coil it could be a bad part you replaced it with. Just a thought

Oh another thing...I'm too lazy and busy nowadays to re-read other people's posts, but has anyone mentioned the possibility of a clogged catalytic converter?

I had a broken wire in the harness going up to the injectors that would randomly cut out one of the injectors....took me forever to find. That broken wire really screwed up the idle and it made it miss bad while running. Just a thought
