took my car into the shop today for a tune up, and i found out that my timing caps need to be replaced (sounds like a hole in my muffler..real poor raspy sound) would that be the reason for the sound & where is it located? because i am going to drive over to the dealership and buy the caps if its the problem, but id like to know where they are located, top, middle and bottom (so says the mechanic)
