All coil packs are working good and I still have this problem! Does burble away popin quietly to itself on warm idle now plus doesn't hold a steady rev on idle also does alot of engine viberation aswell
As above my beams altezza has started to sound like a Subaru on cold idle. Its fine when I drive it and goes away when its warmed up after a drive! IV reset the ecu, cleaned maf sensor and plugs are all ok.
