Sorry Tony, I hadn't seen your e-mail, but have now. From what I understand the problem occured suddenly, i.e.nothing had been done to induce it. The plugs are unipart. The ecu is obviously opening up the ISCV, would RFI from the coil cause this? Will this show up by 'scoping the primaries? Unfortunately the car is some distance away, and I haven't the facilities to do a re-flash. We are trying to keep it out of the clutches of the local, unhelpful dealer, suspecting that if we suggest a re-flash he will land up with a new ecu regardless. I will try and get back to it in the next couple of days and see if anything else becomes apparent, thanks for inputs,
Peter
