Ok, so far this has me stumped. My VLCT manual is playing up real bad right now and i'm not sure why. On idle it's running real rough, and I mean rough. Car shakes on idle, theres this ****ing knocking sound that's only there on idle, you open the throttle and it goes but it its alwayse there on idle. When driving, theres like theres not only a MAJOR lag but also a huge lack of power, it struggles to get over 80kmph, and when you drop the clutch fr a bit of wheelspin it dies in the ass end after **** all time. My clutch is making a noise but i'm assuming that it just needs to be worn in as it's brand new. some of the knocking at idle is because of that, because when you step on the cutch it goes away for a while. I've swaped the AFM over thinking that could be it, and it's still doing it. Siphoned the fuel tank, ran 98 octane with fuel system cleaner through, and changed the fuel filter over but it's still doing it. Changed the oil + plugs over to no avail. Car is almost compleatly stock, standerd turbo, no front mount or anything like that. Any ideas?

umm sorta same thing happend to a car that was brought into my cousionf workshop on wedensday,, tried all the sh|t u did,, ended up being the crank angle sensor... so try that out..

CAS? I didn't even think to try that, makes perfect sense but. Thanks for the help mate, i'll give that a shot and see how I go.
