Smoke screen when starting

[sratta]

Hi all,
Just a question, every so often when I start my car I get a grey smoke that comes out of the exaust and fills the area around the car, not blue like oil or white like condensation. It sort of lingers around for a bit then disiptes. Any one else ever have this happen or know what causes it, otherwise car seems to run fine.:shifty:
Thanks in advance
S.Ratta

dont know grey...unless its black but just not much of it? Black I believe points to over rich fuel mixture. If you have a leaky injector as others have had in the past I supposed it would cause this on startup!
