Is it normal for a car engine to idle high in cold weather until it warms up?

Yes, but it depends on what "high" means. It shouldn't race, but 200 or 300 extra RPM would certainly be normal. The other thing to consider is the time it takes for the RPMs to go back to normal.

2004 Toyota Tundra and when it is cold before warming it has a rattle in the engine until it warms up?
its possible the pistons in the block shrunk a little due to the cold weather. i recomend using amsoil. it is the best possible oil you can get and will help in cold weather. it will also help your gas mileage and you don't have to change it until 12,000 miles i think. the stuff works great.
