hi, had this renault clio for a while now came to me after having alternator fitted at another garage to cure fault of lights on dash and over reving with no result.the car can work perfectly for a hour then the car revs at 3000rpm with no throttle response until you turn the key off and on again. the fault codes are df038 computer internal electronic fault and df078 motorised throttle control circuit ,component in poor condition . we have checked all wiring and contectors replaced throttle body, alternator and ecu with up to date software after ecu was tested as faulty.the alternator was replaced because fault code df102 alternator power available info multiplexed network came up a couple of times but with no result . any respones will be welcome thanks
