Car accelerate without hitting gas pedal
This morning was -37 celsius here and my car seemed frozen. I went on the
highway with a slight hill when reaching the hill my car would not accelerate
more than 80 km/hr and then when getting the flat road again my car would
accelerate without me accelerating. I put my car on neutral and it made the
same noise as when you hit acceleration and transmission at the same time.
The RPM would continue to increase to 6 (I never get to 6000 rpm).
So I turned off the car.
Any idea what could this be? Anything frozen?
