So posted a while back about troubles my car was having with codes and bad startups. Im now thinking it might be an ignition coil problem. What do you guys think?

Bentley had a repair video for the codes my car was putting up, involving fixing the ground wire which we did.

There's a service bulletin to add a ground to the coil pack harness.

Aftermarket coil packs can cause these codes.

A damaged coil harness can cause these codes.

Yeah the Bentley video I posted is directly involved with their repair procedure for this TSB. This is the repair I carried out. I was really hoping this would be the fix.

Any chance the ground point is bad? There are a few others to use under there. Would ground point really matter?
 
If the ground is clean and you used the point called out in the TSB, the I would say your ground is good.

Aftermarket coils installed? How does the rest of the harness look? How do the rest of the grounds look?
