Hi Steve, no unfortunately, Beverley is nearly as far away as Blackpool! I'm on the West/North Yorks border near Skipton. I'm going to take another look at it today. I think the problem source is at Idle. I'm thinking a slight misfire is resulting in inefficient burning of the fuel. Further up the rev range everything seems to be working fine.
I'll start by re-gapping the plugs to 1mm, and just have another look at the phase sensor setting too.

Also got to sort the ABS now too, but think that's just down to dirty sensors - car was stood for a few weeks, so rust from brake discs has probably stuck to them.
