I have an sti, was wondering if its a problem if a little white smoke comes out when I start it. It is catless.

 

how long was your car catless?

 

How long did it smoke for?

Was the car idling or driving?

What was the weather like when it happened?

Have you changed the gas you use?

Look nOOBs if you are going to ask questions ( which is 100% cool, that's why we are here )........................We NEED MORE INFO, for instance....

Say if you are going to ask a "Why" question, we need the who, what ,where, when and how- if you can. It helps us, to help you.

 

The weather was about 70 degrees, It was when I started the car. It lasted for a few seconds as it was idling.

 

More than likely there is nothing wrong, ever been outside when it is cold and you can see your breath........

 

I also think it was some kind of water vaper.

 

yeah dude i sell subarus, and believe me... when i start up subarus....stis/wrx/f.xt..... smoke always happens...moisture from condensation meets the heat of your exaust. but if you see BLUE smoke you need to like panic. but make sure the smoke is BLUE before you panic.

 

well if you can see BLUE smoke...than you better check your eyes toooooo.....LOL....

 

next question,

OMG, MY CAR shakes left to right when I idle, i'm going to take it to the dealer

 

White smoke=Water....you're all good mike.

 

Thanks

 

blue smoke means cracked heads or some other water related problem. smoke is not rally BLUE mind you...but ask any mechanic BLUE smoke is bad.
