Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.

Did you test for power at the ignition coil to see if it has power with the key on?(at or near 12 volts).

Let me know so we can continue,thanks Pete

there is power
Expert:  peterpete190 replied 9 months ago.

O.k.,do you have a ground signal on terminal 2 at the coil,the black wire?If so if you jump a separate ground to this ground does the misfire go away then at all?

That I have not done I stepped away from the car for lunch
Expert:  peterpete190 replied 9 months ago.

O.k.,if your missing the ground signal this will cause this issue.If you can check this,this will help.You might try adding a ground to the black wire and see if it helps as well.If this does not resolve the issue here and you have power and ground at the coil then the signal wire is not sending a signal to the coil from the PCM (engine and transmission computer) and this is due to either the wire at fault leading from the coil to the PCM or the PCM itself needing replaced.Below is a diagram for your models PCM/Ignition system.
