CHECK ENGINE LIGHT AND LOUD NOISE

2003 Hyundai Accent

My 2003 hyundai accent is having problems. I have been hearing a rattling sound and now it sounds really loud when I I start it, as well as when I idle and accelerate. The check engine light came on abut a month ago, but went off on its own-now it is back on. Do you have any ideas?

First, the rattle is most likely a loose heat shield on the exhaust. Take a rubber mallot and tap on the exhaust with the engine off to see if you can duplicate the sound.

Next, as far as the check engine light, you need to have the computer scanned to identify why that is on. The computer has identified a problem and has stored it in memory. Take it to a nationally recognized parts store and have them check it for you. Most will do it for free.

Let me know what you find.
