Ok , got a prob with my scooby, When it gets hot , when putting my foot completly down and the boost builds up , it get to nearly tops and then stops, and builds up again , its like me taking my foot off and thn hoofing it on again , a right juder it is , any ideas of there problems folks ?

Anything at all .

It is a my97 with 34000 on the clock , and it feels an expensive fix !
