Car rattling
 

when I start my car when my car is cold.. it sounds like its not gonna start sometimes.. worries me..
like click click click click vrooom..
instead of click vroom.. ya know? lol lame examples but yeah
what could that mean cuz when my car starts when its already warmed up i can start it without sounding like its not gonna start.
maybe the spark plugs???

IGNORE ^^^...

when I'm in first gear and i'm just starting off my car makes a rattling noise @ around 2000rpm
sounds like the exhaust is rattling but i don't know. it sounds like its coming from the front of the car. it stops before i hit 2 gear.
can anyone tell me what problems this could b?

if it clicks, that's your starter on the way out

Grab another starter. You might also want to run a voltage meter to the starter to make sure you're getting full voltage when you turn the key.
