Thanks for that, I think we're talking about the same bits of kit and connectors. What's "odd" is that the UK / Europe wiring diagram shows the existence of the "EFI diagnostic plug" but it plainly doesn't exist on my CSK in the same location (normal location) as on my friend's '93 model. (incidentally, the ECU on his, which I think is the same part no. as mine, IS able to read and reset the fault codes using the NAS code reader)
The reason for reading the codes on my part is / was mostly for interest only. I know I have a sticky idle valve, and had a faulty temperature sender (now changed) so merely wanted to see if these had flagged up in the ECU and reset the faults if they had. Having done similar things on the '93 model, it made a significant difference to the vehicle's performance, so I hoped the same might be true of mine.
The only outstanding "fault" I have is that the car is still running somewhat rich. However, there's still a few things I can check (plugs, disti, rotor arm etc).
CSK 109: Genuinely 34K miles, genuinely unrestored, genuinely in need of some TLC.
