Well three trips to dealer, 5 out of 6 injectors changed, 1 spark plug and a top engine flush to break up carbon done. Finally runs fairly smooth at startup. But I don't know if it won't do it again. Kia need to fix programming so the engine does not run so rich. They uploaded the newest software. But now I don't know if I can trust car to not have the problem again when out of warranty and cost an arm and leg to get repaired. It maybe hello toyota or Lexus again.
