Basically, the last two days, when i get out to work at 5:30 am, I noticed a 'cold rattle' coming from the engine. It lasts a couple of seconds. I shifted from 1st to 2nd, still hear it, then its gone.

I start the car mid-day,(any non cold weather) and the car is not making any noises it shouldnt.

Anyone know what the problem could be?

check for an exhaust rattle

imported_slowandfurious

could be cat heat shield.

ok now it happens regardless of the weather but only when i turn on the car. It goes away after a couple of seconds.

I don't know why it would only happen after turning on the car..the exhaust doesn't rattle.but i will have to check this with a buddy to reproduce the sound.

I can almost guarantee you its the exhaust.. is it like a metal on metal high pitch sound? Or more of a low rattle/knocking?

imported_globalc

its more of a mettalic kind of sound..hard to describe with words...i think your right too. the pitch matches the revs...

imported_chris_v2

yeah its a heatshield

imported_globalc

so whats the next step bud :P

imported_BoostedEh2

if its the heat shield...and its corroded where the bolts hold it up...take it off...you dont NEED it

worse case..by a new one if you really want it there
