    Don't guess dude get it scanned, theres probably an asn member close to you that'll do it for a beer.

    If you changed all the coil packs and it's still missfiring it could be an injector fault. But there's no point in guessing

    I would say get it scanned too, my engine shook alot idle, you can see it rocking back and fourth...
    Turned out to be the Air mass sensor, i just unplugged it, restarted the engine and it went back to normal. Can run like it for abit, but would recommend changing the air mass asap (if that is the problem)

    ...sounds like you spent a fair amount of money before trying to identify the cause, Why?

    Get it scanned. Even if you pay for a scan it can't cost as much as coilpacks, plugs, maf & temp sensor.... surely?

    Leak, you checked all the vac/boost lines? Check all pcv and under the inlet manifold.

    Could also be a HT lead, worth considering.

    Check the loom that goes to the coil packs, you will have to pull all the black tape off and inspect

    Sounds like this is the Spark plug apmlifier to me mate, buy a new one and swap it over or try your mates. It will cause a missfire and it is fastened to the back of your airbox
