I've been getting a bunch of weird noises recently when accelerating. First it was a whistling sound, then a ticking/tapping. It only happens while driving under throttle so I can't replicate it with the car in park to pinpoint the noise, and sticking my head out the window while driving doesn't work too well. I swapped out my Wizaired intake a few months ago and replaced it with a homemade intake. (Rubber coupler->PVC elbow->Filter). Any ideas?
