Troubleshooting Engine Problems By Sound
My Engine Sounds Like …
There is a lot that can be learned by listening to your engine. Is it telling you something important or is it just rambling on with nothing to say? If your car starts to change its tune, you should give it a listen. Nobody knows your engine better than you do. If it starts to sound odd, or even a little different, there could be a problem. If you catch these types of problems early enough you can avoid a lot of time at the repair shop later, not to mention the money!
