Today in 10 degree weather my engine started racing at stop lights - when I put it in neutral it went up to 4500 before I put it back in gear and stood on the brake. Obviously not a good thing.
Lifting the accelerator pedal with my foot had no effect.
Before I got home it stopped misbehaving. After parking I took off the throttle body cover and tested the movement of the linkages. They did not seem to be sticking, but I sprayed WD-40 on the springs and shafts anyway.
The car was recently tuned up.
What else should I look for if it happens again?
