   Change coil pack and gap the plugs correctly. chances are it hasn't been cammed and there is no need at all to run a higher octane fuel.

   anyways, in the higher rpm's misfire (especially when warm) is the sign of a coil pack breaking down internally and or spark plugs going high resistance due to incorrect gap and age.

   Can you update with a new list of cars that you've dusted once it's fixed?
   
   Can you hit 60mph in second?

    Corsa VXR's are shit, I've had this argument on another thread.
    
    End of fucking story.
    
    However, beyond 100 VXR has turbo powahhz right up to 140, whereas a VTS/GTi will only do 127 (showing 140 on the clocks)

    You should get onto some detailing forums. That much dust from such a small car doesn't sound right.

    Aside from you sounding like a complete cunt.
    
    I think it's the lambda.

    I'd expect an injector fault to be immediately obvious from startup.

    If it is actually cammed, I'd be looking at getting it checked over at a reputable garage to make sure the timing has been set properly and the car has been mapped to suit. I very much doubt this is your lambda causing the issue.
    
    If you unplugged the lambda and it made no difference then it would point to the faulty sensor (as it's not doing anything). But because the misfire got worse when you unplugged it, that tells me that it's doing its job. Still, it's a cheap part to replace and might fix it if you're lucky.
