Have a 2004 gx 470 approx 6843k miles.
yesterday started the car. seemed to "miss" for a monent and then white smoke came out of the tail pipe for approx 5 seconds.
Cleared up and never came back. Car ran perfectly fine all day.
This morning I started the car and same thing. After 3 to 5 seconds went away and car ran finer.
What is this?

I do think you have a leaking engine cylinder gasket or a cracked cylinder head.

Hello!
There are two differnt reasons for black and white smoke coming from the tail pipe.
Black smoke means fuel runs rich (car getting to much gas). Check fuel pressure/air filter.
In some cases the white smoke means car is burning oil or transmittion fluid. Have tem checked/replaced.
If you can feel a smelly smoke it can be catalytic converter.
In a worsest scenario if car blowing white smoke it can be engine coolant is getting into an engine cylinder from a bad head gasket ,or a warped/cracked head. So you need to keep your eye on coolant level and check your engine for overheat. Also might be good to check your oil for traces of coolant (on a dipstick it would be a milky substance mixture of oil and coolant).
Good Luck

Hello There
White smoke when first started is normal. If white smoke continues you have an internal coolant leak, i.e., cracked head/blown head gasket.
Black smoke is caused by a rich fuel condition.
Blue smoke is caused by oil consumption.
You need to check your oil cap for yellow/white gunk on the cap if you have this then this is a sign your head gasket is cracked. Check to see if your radiator coolant level is down this is also another sign.
Hope this helps. Please don't forget to rate me.
Many Thanks

If there is no loss of Coolant, which is a sign of Head gasket failure to the combustion area, which generates white smoke, I would recommend after 4000 miles of your mileage alone, a complete Service of Engine Oil and filter, AIR filter and Fuel filter.
An inexpensive way to find a recurring combustion problem, At 60k miles, the Spark plugs should still be good, but pull them anyway, just to confirm.
