Thanks Craig,

I suspect you are right (and I'm no mechanic either but at least my father was) - the injectors were my next port of call. Seems to me its got to either be injectors or control of the injectors (ie computer). Will pull them out and get them cleaned and try again.

There is a slight wrinkle in that the car is in Auckland, NZ and I live in Sydney, Australia and therefore I only get to attack it when I'm over there (all too infrequently). Hope to remedy that problem soon by freighting it over, once it has been repainted (half the cost of doing it here!).

Cheers,
Daryl
