thanks for the info but my engine is an aum and there is no ignition amp due to being built in to coil pack, measured voltage across each coil pack and cylinder 3 is reading more than the others so im thinking it could be something todo with ecu   :cry: any ideas??

already changed plugs and coil packs but i know its not them now through testing incoming voltage so does anyone know if there is anything between the coil pack and ecu or is it a direct link?? :sad:
