Hello
May you please let me know what is this fuse for?

I was suffering from black smoke and jerking and rough idle after changing many sensors and injectors. I found this fuse blown and changes it

Can it be the cause of that ?

Its wires are green and white / red

after you changed fuse there is no more rough idle or black smoke?

I noticed that the engine became more smooth and didnt have a chance to notice the black smoke

Is there any fuses related to engine or ecu or sensors in this area ?
