Hi Steve
Thank you very much for replying to my sos. Yes he does have a good code reader and it is the throttle body that it says is at fault. He has been told by a guy who has '3' ( dead ) S types all with the same problem and is suggesting somewhere in the mass of wiring to the main is possibly a problem. Too much for me I'm afraid but I will send him the pdf you have kindly sent me and see what he can make of it. Thanks once again I am really grateful, I cannot bear the thought of it ending up on the scrap heap.
Kind regards
Trevor
