Well, the car's driveable again.
Unfortunately when we put one of the refurbed injectors back in it decided to break - the end came off pissing petrol everywhere. I had to buy a new injector, which wasn't cheap but at least it works now.
It was tuned yesterday. Still sounds like a tank but must be the cam/exhaust giving it that note.
Just a small bit of welding left but MOT is next Tuesday. Had to be re-booked a week later than planned as the injector broke.
