i have had the car in a garage they changed the coil block and all plugs
fault keep saying cylinder 3 misfiring when light is reset itsays no fault found
as soon as i drive it away the light comes on again and car is driving very shaky

replace the plug leads ... check the injector on cylinder 3 .. a bad injector will cause cylinder misfire !
