My car is making a rattling noise when idle and when I start it. It goes away when I’m driving though. Here’s how it sounds: [https://www.youtube.com/watch?v=9lV\_ekxbGwU](https://www.youtube.com/watch?v=9lV_ekxbGwU) ---

That’s a loose heat shield somewhere along the exhaust system. To fix you get under there, tap and poke to find the loose piece. Then use a sheet metal screw or even a piece of wire or coat hanger to hold it in place. With a little improvisation this will cost no more than a little time. I advise against removing any heat shields. They put them there for a reason. ---

**“To fix you get under there, tap and poke to find the loose piece.”** +1 However, I think it is important to note that circuitsmith’s advice should only be acted-upon when the exhaust system is **_stone cold_**. ---

How much do you think a shop would charge? ---

Had a broken clamp, making a rattling noise like that, my regular guys said no charge, bender shop welded a split cat for $10, along with exhaust system, My guess $50 max and probably less at an independent shop if it is exhaust related simple fix. ---

Sounds exactly like my travel alarm! Most shops today charge a minimum one hour diagnostic charge. Often with a loose exhaust part that only needs a clamp, they’ll only charge for the labor, sometimes only a nominal fee. Thanks for the video, however. I wish more posters would take the few minutes to give us real detail. It really helps. ---

Do you still have the rattle or is it fixed ? ---

Update! It was the catalytic converter! I got it fixed on Saturday.
