Hello. Hoping someone can help me diagnose this mildly annoying issue that I've been having.
When stabbing the throttle around 2.5k-3k rpms I'm hearing a faint whistling noise from the engine. If I gradually increase throttle there is no noise. Sounds like it happens when the throttle body is opening. I've checked around for any vacuum leaks but all looks fine to me. Engine is stock, intake is enclosed with a custom lid and car has gt4 louvers so any engine noises will be exaggerated. No check engine lights and A/F ratio seems normal.
