Hello everyone,I m from Montenegro,sorry about the English....
So lets skip to the problem: When i rev the car at idle at 2700rpm,or over it starts to make a tickling sound...But when I turn the fuel pump of on the conection cable and then rev the car there is not that tickling sound.So I losed a litle the spring (i dont know how to call it) on the top (black part) of the pump i didnt removed the pump.Then the sound would start at 4000rpm at idle,that didnt disturb me...but after a few days of driving the car would lose strenght and wouldnt rev past 3000rpm.
So my mechanic removed the HPFP,and took it apart.He said that the previous ovner had done something to the pump so it didnt work well,the parts inside the pump werent original.
Today I bought a completly new pump,cam folower,and cam sensor.We replaced the old one with the new one and the tickling sound is remained the same 2700rpm at idle,and 1700rpm at driving,it is very anoying...
So my question is simple: Can i lose a little the black spring(i think that this is the regulator of the preasure) to remove the sound,because the pump is new i didnt do that without asking?
PS: the camshaft isnt the problem it is like new.
And i forgot sometimes it shows some errors p310c,p310b
I would be thankful if somebody could help me about this problem....
