Well I know I connected them wrong first off as when I started it there was a bit of a pop then nothing, now I've got them in the right order when you start the car it doesn't idle that well, very shaky and sounds like a tractor and if you go by the exhaust you can smell petrol I'm guessing when its not being burned, need to change out the plugs but the tool I bought is to bloody big so need to replace that for a thinner one :p, ill try and upload a video I took but my blackberry saved it in a odd format so need to get that converted
