Hey all,
I have a 1990 4WD with the 3VZ engine. When I rev the engine up and then release the throttle, a low rumbling sound comes from the air filter compartment. It almost sounds like a growling. It happens all the time and the air filter is clean. Is this normal? Any ideas as to WTF this sound is?
Thanks in advance.
