I have a 1999 Ford Escort, five speed. Until recently, I have not had any issues with it, but its age is beginning to show.
This past week, I've noticed a rattling noise from under the hood when idling, such as at a stoplight. Once I start moving, I can no longer hear the noise, though it is possible the road noise is hiding it.
Any ideas on what this is? Is it serious, or just an old car making noise?
