Does anybody know what this sound is? Just did new rotor/pads and an oil change. No leaks and oil level is just right.
I hear it when driving and when it's idle. After going out to bed brakes my car shut off by itself when I came to a stop in the garage so I'm worried about driving it.
EDIT: Car now sometimes fails to turn on and when it does, it dies immediately. CEL is on for system too lean. I reckon it's a vacuum leak.
