Thank you for the helpful replies:
-Tim: I'm running it on 97 and have (sorry to put it this way) wrung its little neck out quite regularly (once properly warm of course!). Very good point on misfiring, I will sort a code reader and see if that's happening.
- Rog: you are quite right, it's new to me, bought second hand from a reputable dealer so under warranty -- dealer is five hour drive away, however, so thus wondering if this is just normal cold start for a GDI in a Morgan.
- Paul: about 1000 km in the prior 12 months, so I guess on par for a Morgan. I've managed to add another 1000 in the last two weeks (hard to stay out of the thing, my wife getting a bit concerned I think...)
