Im having the same problem with my 'H' reg sapphire Stage 1, i have been told its something to do with the timing

 

what plugs you running in it?

 

Garry, could be loadsa things, mine does it too... have you searched for misfire on here ? There's a few evening's worth of tinkering you can do, maybe it'll fix it, maybe you'll be back with the same question.
Mine's going to a pro, scratched my head so much I'm gonna have holes in it soon.

 

yeah greg gonna have to take mine to be set up real soon me thinks

 

Fancy a group buy ? I have two to take in
