colder plugs
just recently install some one-step colder plugs and now the car starts sluggishly, idling roughly jumping and falling until it picks up later but drives normal, just wondering is that normal for colder plugs or did i do something wrong, thanks

550cc injectors are the problem.
The car needs to be dyno tuned now with -HKS / UTEC / HALTEC -ect.

your tune is off, do you have an afr gauge? probably your combustion mixture is flooded with fuel.
