Mine smokes white until it warms up also. Figured it is normal.

It generally is pretty normal however mine went from noticeable to excessive and I decided to take it in. I ended up have 2 bad injectors which were leaking or something to that effect (I'm not a mechanic) and now the problem is solved. That was my solution but I know that there's other culprits for excessive white smoke upon start up.

Smoke is usually lazy injectors....
