The most common causes of the unstable work of the Renault Sandero engine at idle are the pollution of the idle governor and the leak-tightness of the inlet pipe hoses.
If the hoses are hosed by hoses and the cleaning or replacement of the regulator has not corrected the problem, a control system sensor may have failed.
If unstable idle speed is also accompanied by engine rods in other modes, the throttle position is likely to be a problem in the throttle position. If there is a decrease in the capacity and the increase in petrol consumption, the oxygen sensor in the exhaust (lambda-probe) is probably not available.
