Edorfox, I just want to say I hope you find out what your stuttering issue is. I really did think it was the coil-pack in your situation. One thing I should mention is that I did place a 4-guage ground from the ground point on my new coil-pack as well directly to battery and I replaced all the grounds to frame and battery with 4-gauge replacements. Again, If I think of anything I will post (along with Warmonger). TtYl.
