Accel Ignition Coils
In my opinion, replace them. If they are not within factory spec, they are probably effecting performance.
About a year ago I bought Accel ignition coils. My factory coils were within tolerance, but I replaced them anyway. I did notice a slight gain in performance over stock. But maybe that was a sign that my factory coils were indeed, going bad. Or maybe they are better. Anyones guess. Good luck.
