Did you still need help?
How does the engine run? How does it idle and accelerate?
If you were to clear the codes, which one would come back first?
And you replaced the number 3 cylinder ignition coil pack? Are you sure it was the number 3 cylinder coil that got replaced?
If so, does this coil pack have power to it when the engine is misfiring?
SO your saying that the the engine still misfires on number 3 cylinder even after that coil pack was replaced?
Or are you saying that if you disconnect number three coil pack, the engines idle drops because the engine starts misfiring?
As for this code, there are only three things that can set this code.
A bad COP, a bad wire/connection or defective COP driver in the Powertrain Control Module. IT is as simple as that.
Verify that the ignition is maintaining FULL battery voltage on the White/Violet wire with the engine running.
IF so and this code continues to set, then run a new wire from pin 78 of the PCM Orange/Yellow (O/Y) to COP #3 and retest.

Sorry for the delay!
NO... only if this code keeps appearing or if this coil is not firing due to a signal from the PCM, then run a wire from pin 78 of the pcm to the ignition coil number three.
The white/violet is only power to the ignition coil. THis needs to be checked first. The pcm wire cannot be shorted to power to at at the ignition coil.
