Have a question about coils

I just bought 6 new ignition coils and I change them all. But I heard that they needed to be coded or programmed. What will happen if I don't get them coded or programmed ?

Just the injectors need to be coded. Coils are plug and play.

You should clear adaptations after doing plugs and coils, especially if you are changing them due to a drivability problem.

On another note how bad is it to drive on an injector thats not coded? I've been driving all day today on a non-coded injector cause I can't get it done until Monday... I've been trying to drive very gently but did push the car a few times

I have been driving with an injector not coded for the past 6 months, no issues at all,that injector is just a little louder than the others. No problems, pulling hard.

That's definitely a relief. I'm getting it coded tomorrow anyways but I was just worried it could have messed something up.
