I have aMegane 05 cuting out on idle when cold and jerking on gear change and take off. I got it checked as thought it was coilpack but checked and coilpack was ok. The car then started juddering so caslled out the Aa who diagnosed on fault as coil pack misfire cylinder 2. Colil pack changed but still cutting out on idle when cold and stil jerking on take off and gear change intermittently. AA advised to take on a long rum on motorway to thrash out any sut clog up etc in fuel system etc but stil the same. Can anyone help. Thanks
try cleaning your lamda sensor - i've had it happen on a couple of cars - it's a sensor in the exhaust that gets coaked up. if you cant clean with a wire brush they are cheap to replace.
