If it's knocking when accelerating, the engine could be starving for the correct octane fuel ... try the mid-grade or premium fuel and see if it still occurs. Could also be that the timing belt needs to be adjusted/replaced.
If the knocking sounds like metal on metal, chances are you are in for a bigger bill for a possible engine rebuild. At any rate, have it checked out by a mechanic soon.
