Hard starting and stalling immediately after starting warm engine

Hard starting and stalling when engine is warm or when weather is hot

Hello Scotty,
Profuse thanks to you for all the help you provide people. I asked you a few days ago about a hard starting issue my Toyota Corolla 2013 has for more than 6 months. This is what happens. In the morning the car starts right away though sometimes i hear some noise that last for three seconds then goes away. After driving for a short trip i park the car for, say, two hours then i try to starts and it cranks longer the normal then starts; sometimes it starts in the second cranking.I have replaced sparks, fuel filter, air filter, and cleaned MAF but in vain. Now as weather is cold, the car starts often with some slight stalling while being started. I am attaching vidoes for the case i have.

You, in fact, recommended cleaning injectors, I am wondering whether you could possibly explain how hot condition affect injectors .https://www.youtube.com/watch?v=NB4h48L5EqI

Thank you very much indeed.

if injectors are dirty, spraying too much gas from dirt making nozzle spray the wrong pattern, it can start fine cold, but not when hot. Cold engines, too much fuel actually helps.

Interesting Scotty, thank you very much. I am going to clean them soon and come back here. GOD BLESS YOU.
