I'll check the ECU number in the morning if I can find the box of bits that has been changed. 937 sounds familiar though. However - - - she had a new lambda sensor during one of the very first attempts (after the head gasket) to cure the misfire. I remember the rueful look on the face of John the garage proprietor - who was a staunch methodist and would never lie or mislead - as he said "When I looked at the state of the old lambda sensor I really thought I'd solved it, but then I put a new one in and it wasn't that".
