What could cause this?

 

What color smoke is coming out?

 

^^ Yes, color of smoke you are seeing helps.

Once you find that, google "XXX smoke at start up"

XXX = the color you are seeing.

Let us know what you find.

 

White smoke = coolant. Blue smoke = oil. Red smoke = someone punk'd you.

Mine does that too, but mine is oil smoke. Once it warms up, its good to go. To stop this, I use a can of "Restore" every oil change. Pour directly into the crank case and drive.

It's worse in the winter, I've noticed. Restore makes it stop completely.

 

It's a light grey/white'ish smoke... it comes out while driving too if I get on it to accelerate....
