It just started happening recently and only when the car (6MT) has been sitting for a while. Car has 12.7k miles. When I start the car and take off in first, usually just letting out the clutch slowly coz the engine is running around 1200rpm with no gas, I hear this squeeling/screeching sound. It sounds just like the high pitch sound from brakes squeeking, but it's not the brakes since I'm not pressing them. After like a minute of driving, it doesn't squeel any more when taking off from a stop, not until I rest the car for a while and start her up again. Any ideas?
