Jim 2 Posted March 4, 2014 Guessing its a VR6 as you mention coilpack but ensure the leads are connected to the plugs properly - they can be a bit stubborn on the VR because of how low down the plugs are. If that doesn't work try alternating through the plug leads swapping them with your originals and see if the misfire goes away. Were the parts all new or second hand?
