I have a opel corsa 2006 1.4 sport avreges under 1000 rev when idle and the idle goes between 1500 revs to 2000 revs as the car is being driven and stops. what do I check for or what could be the cause?
Check and clean the iac valve just behind the throttle body. If there is some dirt or dust clean it with a light dissolving solution. Nothing harsh.
