Hello Fellas and/or Ladies,
I noticed that when I turn on my car it's a little noisy when driving and idling. I started noticing it during the winter but not sure if it sounded like that during the warmer months. I would like the car to sound like newer cars do, relatively quiet. What could I adjust or change to make the car quieter than it is now? Thanks guys

 

Your tires are likely worn & are causing road noise.
Without something better to go on, that's all I can suggest.

 

My CL is 6 years old, nearly 90k miles on it and I've never found it to be noisy, idling or driving. I agree with Fuzzy that the most likely thing is tires.
