Why do my RPMs go up when I brake going downhill?
If the transmission is engaged and the engine is connected to the wheels, as the wheels pick up more speed due to gravity, the engine RPM goes up during a downhill descend. Some people have a misconception that due to more RPM, the engine consumes more fuel. Hence they disengage the gears and put it in Neutral.

How does Hill Descent Control Work?
Available Hill Descent Control is essentially a cruise control system that uses traction control technology with anti-lock brakes. This system continually adjusts braking pressure to help control slippage and maintain a constant preset speed while you are going down a steep grade.
Why do my RPMs jump while idling?
An idle surge can be caused by multiple phenomena. The idle air controller is simply a computer-controlled motor that controls idle. There could also be another sensor that is telling the computer to compensate, and in turn, this causes the idle to surge as it looks for the correct RPM level.
