Starts laut at a temperature Toyota Vigo 2006

KIND REGARDS. Toyota Vigo 2006 310,000 km
The start when it is cold is fast and normal, but if it is heated at normal temperature, the start that even plays 2 starts so that it garments, all the basic maintenance is done, what I notice is that in cold In the scanner I do not boot any code but I think that it is the tempera sensor that gives order to the thymer of the spark plugs so that the preheating time is short, saven which is or what are the sensors that control the timer of preheating of the spark plugs
