Engine doesn’t work smooth after staring

[Skyjafangari]

Dear All. I am new here and having an issue with my 1,6 156kM RCZ baby from 2010
Generly after starting the engine the engine work is not smooth - the car is shaking the engine speed is variating like choking - the air sucking is irregular - several times the engine diode is lighting - once engine is heated the problem disappear. Any hints ? I have the move of this issue and can send to anyone who want to see the engine behavior

thank You an appreciate any help

These shaking are usually due to miss firings, the engine starts with only 3 or 2 cylinders and the probable cause is a faulty high pressure fuel pump.
