Weird Sound when start-up

advans · 01-13-2011, 02:17 PM

Hey guys,

I got this weird sound when starting up the car when its cold out.
It's this weird clunking noise for maybe 1-2 seconds, then its gone. Any Clue?

I don't have any weird sounds

that sounds is normal. i think it's just the cats warming up or some other parts warming up.
