Hi my poorly s3 has gathered a problem
Started juddering and misfiring below 2000 revs and idle. Plugged into vagcom no fault codes except intermittent misfire. Dug further cylinder 2 keeps misfiring changed the coil pack no change, new spark plugs no change, cleaned injectors and moved no2 to 4 and still misfire cylinder 2 checked injector 2 wiring all is well so I have drawn a blank any helpers thanks
