Lol not much good luck hey? If you think its on 5 cylinders then when its idleing, unplug each coilpack and see if the revs drop at all. If they drop, that coilpack is working fine, if they dont drop then that coilpack / sparkplug inst firing properly. Hopefully you will just have a loose clip like i did. Also u sure its not a missfire? As heaps of 33's have missfire and idle problems for various reasons. Hope that helps you. Good luck with it..
