Thanks for your response, Bertrand. The service was done privately (by Steptoe on the ukgser forum) who knows his stuff and the idle issue has him stumped.
1. Without the PC it doesn't stall but the idle is rough. Here it is on video, without the PC:
YouTube - ‪07 GSA rough idle‬‏
The PC was installed correctly, has a custom map and I've greased the connectors. I thought it was a PC problem at first and Dynojet sent me a replacement, but the same thing happens. For some reason, though, it's worse with the PC as you can see from the first video.
2/3/4 - all taken care of at the last service (2 weeks ago.)
5. Looks OK.
6. Don't know.
Looking around other forums, things that might be factors are
Stepper motors
Crank sensor
Vacuum leak
Do any of those sound likely in this case? The intriguing thing is that the PC makes it worse but is not the source of the problem!
