Fluttery noise instead of DV noise.
Over the last week or so i have been occasionally getting a fluttery noise when i let off the throttle.
Where i usually get a nice clean/ crisp tsh....
I assumed i had a boost leak, so today i smoke tested my system.... It was fine, bar a little seap around the oil cap (is this bad?)
It held a constant 10 Hg02?..(whatever that means)
My next thought would be the DV (007p) but running a yellow spring i assume it wouldnt flutter?
Its a very difficult noise to describe, Almost like a heatshield rattle but more plastic-cy.
And help or advise on what to check next appreciated.
(Tomorrow im going to stick the mityvac on the DV see if its holding vaccum)
