301T Trouble - MSD 6 BTM???

[mike brush]

I've got a 1980 Trans Am with a 301T...
It has never idled well and dies at every stoplight
unless I rev the engine above 1,000 RPM...
I just installed an MSD 6 BTM ignition thinking that
might solve the problem, but it runs even rougher...
Any suggestions on what might be the problem?
Does anybody know how to wire this ignition up correctly?
I thought it would totally replace the ESC system,
but installed according to directions, it just seems to connect into my existing set up...
Any help is appreciated!!!
