Yes. The spring closes the throtttle. Your foot has to overcome it. Toyota had some engine failures with a Yamaha designed 4 cylinder for the Celica in 1999. The solution was stiffer springs in the shifter. People would put the car in second instead of 4th going 80. The oil pump would come apart, and the engine will seize without the oil. Nothing actually wrong with the engine or pump, operator error.
Interesting.
