I'm hearing a very faint knocking while cruising whenever I give light throttle at low-ish rpm. Sounds kind of like a woodpecker, but it's very faint, barely noticeable, so much so that I think it maaaay be normal? Not sure... It's very responsive to the throttle, like instant noise as soon as I press it. Does this sound like the injectors? I'm considering upgrading the nozzles, but I'm wondering if I should maybe try some kind of injector cleaning additive first, see if it does anything. Anyone has any success with any of those?
