Renault Megane 1.4 16V 2003. 98 hp
Strange idle when coming to a stop.
Changed ignition coils and sparkplugs and also cleaned throttle housing and still no answer to this problem.
Battery voltage is 12.4V when the engine is off, and 14.2 when the engine is running. Also it's strange that engine is reving at 1000 rpm when hot, it should be around 800.
Local car mechanic thinks it need new throttle body.
No fault codes.
Any advice ?
