A control assembly and method for operating the throttle of an internal combustion engine, in particular, but not exclusively, a diesel engine of a heavy duty vehicle, is provided whereby fuel can be saved by controlling the throttle operation and a driver can be trained to exhibit better driving skills. Detector means detect certain undesirable throttle conditions or movements such as full throttle for an excessive period of time; the number of times a throttle is pumped; and the speed with which the throttle mechanism is moved, and the assembly acts to reduce the fuel supply to the engine to an extent whereat the engine does not lose engine speed to any appreciable extent at constant load, but full throttle is temporarily unavailable.
