i just wanted to clarify something for my own piece of mind really. my fpr seams to make a sort of squeely noise now and again, sometimes its always their sometimes it comes and goes on idle, ive tried to sit ot as flat as i can on the arm its fitted to. does an one else get this? or is it a sign its gonna die? i obviously dont want to then run lean as i dont have an afr fitted yet.. cheers lads
