new coils
i have searched all the first gen threads and only find info on dfis systems, my question is will my stock fb run better and get better spark if i replace the coils with brand new ones. the car does run ok as i am heat cycling it after a rebuild. im just curious if i should spend 80 bucks on coils, to see if it runs better or stronger spark.

Paulieboy72 To answer your question about replacing coils, you can use a multimeter to test the resistance (ohm's) of your coils. Spec is 1.35 ohms give or take 10%. I have found that most of my original rx7 coils are often out of spec by multiple ohms. So I ordered some coils with the proper amount of resistance.
