Checked spark output at coil pack and found that the left side of pack is generating a stronger spark than the right side of the pack. Is this an indication that the coil pack is breaking down?

Hahaha........

No, it's all the same spark. It goes out through one and returns through the other. Just a big loop back to itself.
