Purchased 2/04. hesitation problems since first month- found nothing wrong. chnaged oil at 5000k miles, checked again, found nothing wrong. now has 7000k miles, still hesitating at various speeds and has begun not starting. towed to dealer, fuel pump replaced due to weak pressure. two days later, would not start and hesitating still. towed back again did start, smelled bad, but no codes or problems found.*ak
