engine hot or cold

This is the picture of the coil pack, I am not sure if I can try the screw driver test, I am afraid can blow the module. I will do what Tech2 is recommending, will clear the DTC and drive it to find out when is on again, will report back after the tryout. I know that this kind of vehicles clears the code after 3 cycles of code not being present so I am sure what I have done has'nt worked.
I did clean the injectors with an AC Delco additive.
I am reluctant to change the coil, I am not sure it will fix the issue.

Misfire occurs on cold start
when its misfiring the engine will exhibit a shake which you can see with the hood open. there will be a lack of power when driving.
