The trailing ignitor blew so I installed an msd 6a ignition firing independant coils to both leading plugs, and used the old leading ignitor in place of the bad trailing ignitor. I have much better throttle response, it pulls hills with ease without having to downshift, and the plugs are staying clean so hopefully I may get a couple of more miles out of them

 

what year is your car?

 

Something here is wrong...what year RX-7 do you have?

The leadings fire together, but the trailings do not. You may have radically messed up your ignition timing by reversing the triggers.
