Injectors need replacing in GTA - Squeeky noice when idle

I hear a squeeky noise from the injectors when idling. The Alfa tech said its common for v6 alfas to have loud injectors...I really dont believe him maybe cause it will cost them a bit to replace?
Anyone elses alfa idle rough?

Nope not me, I've never heard of that complaint on this forum either. I think the mechanic was being economical with the truth, try another dealer and see what they say it is.
