TOYOTA RAV4 05 '2.0 DIESEL MOTOR D4D

My RAV4 truck, since Buy has the characteristic that when starting cold or temperature the engine turns a lot. I do not know if it is normal or I must make some part especially. Scent comments.
SLDS.

They can be the injectors that are somewhat clogged

But the injectors work all the time, not only at the start ... that is, it has no problem in acceleration, power, does not smoke, etc.

Hi Roderick.
It seems to me that if you should have a little smoke when the fault occurs and that you have not noticed because it is only at the start. If the smoke is white, it is due to an excess of condensation and is water vapor, which disappears to the second or third working time, if gray it can be an injector with low fuel delivery pressure and that normalizes by accelerating and acquiring its normal working temperature, in none of the cases it is serious, luck.
