Haven' brought the car to anyone yet. Googled the symptoms and the problem is most likely a problematic lambda sensor. Seems it's just like a spark plug replacement, reckon I can handle that! Inventing the wheel is not always the easiest way but there’s satisfaction in it. If I can't work it out, I will have to go to the expert. Reckon the guy in Bishopstown Autos could be that guy since he sells these cars and probably knows all about them. I do know another guy who is in every sense a car guru and I might run the problem by him if needs be. I'll let you know how it goes and who I use if it comes to that.
