This seems like a silly question, but is it normal for a 2001 Accent's engine to give a rattling sound on a cold start? I had not noticed this before because I normally have my window up when I start. Basically, if I start the car after it has been sitting overnight, the engine idles with a rattling sound for half a minute or so. It fades soon after, and will not recur until the car has been shut down for a long time. Googling on this issue pulls up a whole bunch of possibilities for a whole bunch of cars, but for some cars, this is supposed to be normal. Is it?
Thanks.
