While im driving and the car is warm/heated up completely, sometimes I throw the car in neutral going down hills on highways or roads and the idle will shoot up to about 2800rpms and stick untill I come to a complete stop. And on top of this there is significant power loss as if there is a misfire. But when the car is cold the power loss doesnt occur. Only when completely warm.
what might be wrong?
