Hamwich - my plus 8 is ‘94 so possibly the ‘worst’ mix of restrictive injection and cat determined emission regulations. The annual struggle to pass the MOT involves a spare MAF, it makes the car run really badly but meets the emissions so that’s fitted just for an hour then removed. Maybe the tornado chaps can manage to solve this problem too.
Yeah sorry, I was forgetting just how comparatively dirty those Rover V8s are. I was thinking from the perspective of earlier less restrictive emissions requirements being much easier to meet with more modern engines. But hopefully a revised management system should be able to help.
