code 43 = "Ignition coil control circuit or spark interface circuit- out put stage not responding to control command"

I was originally getting a "miss fire on 2,4&6 cyl" so I replced plugs, wires.
Then got a "multiple misfire" code and replaced the coil pack.


Now, I'm getting the 43. Any thoughts on where to go next?
Does anyone have a "trouble shooting" tree/ diagram for these cars?

Thanks in advance.

It sounds like you you may have gotten a bad coil pack. Try one more and see what happens.
