Have this checked out before parts replacement. Mechanic with a good scanner can save you some money! There are a few possibilities for rough idle. Only 24,000 miles,, most likely a vacuum leak. Obviously sets around a lot, check for any signs of mice under hood, they love to hide out in engine compartment and chew on vacuum hoses etc...
