This only happens when i first start my car up on a cold morning. I have an 03 6sp and it also happened with my 00 5sp. When i start my car up on a cold morning and the rpms go up,it makes a wierd sort of grinding/ticking noise. Its only for about a second while the rpms reach its peak during the start. I have no idea what it could be. Its not wicked loud, its just loud enough so I can notice it. Like i said it only occurs when its cold and the car has been sittin there, its during the initial start of the car when the rmps go up for a split second

 

it's your timing chain

 

belts warmin up.....

 

nothing to worry about. It happens to me too.

 

so its probably nothin to worry about then?
i meen its only lasts a second

 

yes, nothing to worry about.

 

Same here. Didn't happen to me in the beginning tho, just last 6-7 months.

 

ya this was discussed a lil while back. i think people determined it was the timing chain, as mentioned above

 

I believe it was the VTC sprockets. VTC = valve timing control.

 

yeah it just started happening to my 2k, its really annoying.

 

has anyone had this problem fixed?
