Thought I'd carry on the theme with this, seems slightly different to the others.
I am getting a random surge in revs, around the 3k mark and usually in 5th gear, when accelerating. Will shoot up to about 4k, engine note changes but there is no difference in the power generated. My suspects are either an air leak somewhere or a slipping throttle cable. Does anyone have more info before I start poking around? It's an 8v Digi.
Cheers
Steve
