Hello all just bought my first scoob but had it for three weeks now and its started to become slow and sluggish it really takes its time to build up speed and staggers untill it gets to 4500 revs where it starts to pick up ive had a service on it and changed all the plugs and filters but its still slow its a 1999 UK Turbo

 

Are you running normal unleaded petrol?

Try vpower or tesco 99 and it will spring to life.
