Cleaning the throttle will help to avoid high differences of speed.
throttle unit are closely linked with the idle engine speed, if
idling is bad for the first possible cause is the throttle
it requires a thorough cleaning, the second reason is the idling sensor and the third reason is a regulator of idling.
You can still throw off the terminal and unplug the computer for 3-5 minutes then reconnect
the place and the rpm returns to normal banal errors of the sensors.
