Technical Fiat Sidici 1.9 Mjet bad iddle RPM

[nikitoo123]

Hello I have the following annoying problem. When the car warms up to 50 to 80 degrees at idle, the car knocks and runs unevenly (as heard on the video). When I start it in the morning or when it warms up to 84-90 degrees, the motor starts to work properly. Or if I have to pick up the rpm it is heard that it binds around 2200 2300 rpm and you watch as 2300 rpm knocks a spiral. I had doubts about 4 injector,but I change it,but the problem remains. Look Video in text document.
