Conversation Between Bluegrass 7 and jhowel34

I was reading a post that you had commented on about a shudder at 40mph due to faulty coil pack issues. I am having the same shutter issue around 40mph with mine and realize it is probably a coil problem. This may be a stupid question but my battery is really weak and I am trying to delay getting a new one. I read somewhere in here about low voltage at the coil cause it to miss read could a weak battery possibly be causing this problem? I never noticed the problem before my battery was weak.
