Hi Kim
I know I will have to go to the stealership for a diagnosis

, but I am trying to get as much info as possible on probable causes so as to be technically able to question their diagnosis. I have not got the bucks to let a dealer try and fix it. It has to be right first time...
It seems on our beloved cars there are mainly two problems. Lambda sensor and temperature sensor (the one with the blue connector?). The combination of these two can wreak havoc apparently.
Ciao!
