hi i'm just wandering if anyone could help? i have a renault clio 1999 model 1.4.my car starts first time i can pull off drive but when i stop the car cuts out i have no lights come on dash i've had new bat,alternator,plugs leads, full service ,once the car warms up it runs great.it's annoying me now as when it's cold it will try to cut out whilst i'm driving and you just get a thud and a burst of speed.please help .
Possibly a faulty coolant temperature sensor, dirty throttle body, etc. Ideally a diagnostic check to see what the temp sensor is reading when the engine is cold and also check the idle speed control valve values before and after cleaning out the throttle body.
This should be in Technical and Maintenance really for more answers. (it is there now!)
