    search mate, been covered loads of times... it can be anything really, cables cutting into throttle body/manifold, air leaks, sensors missing...

    list goes on dude...

    best thing to do is to get it to a garage and let them have a look in the ECU, it will say if there are any sensors that are not working or performing incorrectly

    You could start by cleaning all of the contacts for the coilpack also it may help if you reset the ECU!

    with some miss firing all you need to do is just check the fule pipes! if they are blocked in any way it may cause it!
    ECU is the last option! as it will cost u a fortune if you know nothing about it!
