Interesting dilemma presenting itself.
Car is making an odd intermittent chirping sound (not crickets). Mostly audible at low RPM, frequency of the chirp increases with RPM but not in a reliably linear way, and doesn't occur at idle.
Sounds like it's coming from the driver side of the bay.
I'm running a C38, with a Forge Motorsports Recirc Valve, car is at ~70k miles.
Any thoughts on a potential culprit?
