Why Is My Car Making a Rattling Noise When at Idle?
Hearing a rattle as you drive is irritating. What makes it more annoying is that a rattle can indicate a simple-to-fix problem that will cost almost nothing to repair or a significant issue that could cost thousands of dollars to solve.
When you hear a rattle when your engine is running, but your car isn't moving, it is time to engage in forensic auto mechanics. By that, we mean you look at the available clues to help you determine the answer to the question: "Why is my car making a rattling noise when idle?" Determining the rattle's probable cause is a little more scientific than reading tea leaves because not every rattle is the same. So, by listening to the rattle itself and where it seems to be coming from, you can start to sort out where the problem lies and how much it will cost to fix it.
