Hey Earl,
It sounds like one of two things has happened, either the firing order on the coils got mixed up or you cracked one of the plugs installing them.
Here is a guide and a diagram to help get the problem fixed:

Please let us know what happens and upload pictures or videos of the problem.
Cheers, Ken
