Would anyone have any idea why my ncv3 be making a noise, if revved when cold goes away at about 1500 rpm till driven, when warm revved to about 3000 rpm. Driven on hwy. or when warm most of the time things are normal. I suspect something to do with turbo, exhaust or cooling system. Any suggestion is much appreciated as it is difficult to get good diagnosis around my area or if available its expensive.
