Thanks Justin, I agree totally.
That's why I wanted see if anyone here was able to give me any advice/info; as I wasn't happy with the mechanics diagnosis of "you'll need to get both those oxygen sensors replaced".
Being able to read the codes is one thing, but knowing how the systems work, and how the errors relate to the symptoms of the fault, is the key to discovering what the problem really is.
Thanks for all the input guys.....appreciated.
Cheers
Paul
