    At first, I was not conscious about any noise coming from my car engine but it was really foolish of me. Still I remember that horrible trip of my life, I was all alone at the road side for the whole night. Really horrible! Actually, I had noticed some sounds coming out of my car from 2-3days but I didn’t pay attention towards it hence the result. Well, I had had only little idea on car noises but here I got to know so many different types of noises. Thanks for updating me.
