"Ardor" ("ardour" in the U.K.) means "great warmth of feeling; fervor; passion" or "intense devotion, eagerness, or enthusiasm; zeal" while impetuous means, "of, pertaining to, or characterized by sudden or rash action" (definitions from dictionary.com).
So, impetuous ardor would be intense passion or devotion that is unrestrained or unchecked. It is having fervor, passion, and zeal, and acting impulsively or rashly on it, instead of trying to control it.
