Stuttering

I have a 98 impreza as shown below, but around 60mph and 80mph it stutters really badly, does anyone have a solution why this is happening and if they have experienced the same? its fine driving normally but as soon as i stick the boot down i get this shuddering effect at the speeds above, its so fucking annoying especially when im gettin these little boys in there novas and corsas staying close behind me.

how old are the leads and spark plugs? also it could be your coil pack or it could be something in your fuel......there are 100's of different things that could make it do that, best bet is to take it to a mechanic to look at.......i would look at it but im kinda a bit to far away haha

You shouldn't be going that fast silly... the car is telling you somthing

Does your engine run rough and cut out....or are you just getting some vibration at high speeds?
