A handling condition such that the slip angle (the angle between the
direction the tires are pointed and the direction they are going) of the
rear tires is greater than the front. You feel this as the tendency of
the car to continue to "turn into" the corner even though the steering
wheel is steady. As the car attempts to tighten up the corner, the driver
has to steer out of the corner to maintain the correct line. In extreme
cases, opposite lock sometimes is needed.
NASCAR types call this "loose"
>Understeer
A condition where the slip angle of the front tires is greater than the
rear. It manifests itself by requiring more steering angle on the front
than the corner would geometricaly call for. In other words, you got to
steer more into the turn to get around. Most cars are designed to
understeer as it is inherently safer, albeit less effecient.
Roundy-round racers refer to this as "pushing"
For a much better explination of both under and over-steer, check out
"How to make Your Car Handle" by Fred Puhn.
>Run-on
Assuming you are refering to engine run-on, is simply the engine
refusing to stop when the ignition is switched off. Some times called
"dieseling".
Hope this answers your question.
