   Ok where to start recently my car developed problem reving up and down like yoyo on its own while driving down road. Note it does not do it when at ilde thou. knw i have replaced gasket between intake mani and carb (throttle body) also put some gel type stuff seal it as it petrol proof and all tht. anyway worked for bit ok started doing it again today. and mt actual throttle pedal inside car moves as it does it weird i can take foot of acceleration pedal and it will go itself. Not 100% sure could be ar leak somewhere gonna try once cooled down with carb cleaner. i have 1.1 saxo 2000 model. any other idea i heard could be coil pack problem too. any ideas please say thanks

    if your pedal is moving while its doing it its either the throttle cable or possibly the spring on the throttle body, nothing would make the pedal move inside the car sensor wise

    When the ICV is changed for a replacement unit is there anything else to be done?
    
    Does the ECU automatically re-learn the new part?

    Turn the ignition on and off 6 times waiting 10 seconds or so between each time then start the car on the 7th time, this sets it to the right position

    I had this one a 106 gti (same engine as VTS btw)
    
    Did this (in this order):
    
    Cleaned ICV
    Replaced MAP Sensor
    Replaces Temp Sensor (Green Plug)
    
    It was resolved on the last step
