It doesn't affect all cars but is fairly common when you have potentially old plugs/coils that may be working fine under stock conditions.

Thank you for the reply! The previous owner kept it in great shape and took care of it with all scheduled maintenance so hopefully I won't see that problem. I also might be puttin. In a bms intake. Does anyone know what kind of gains I'd see with stock setup but intake and axleback exhaust is installed?
