Thanks for the response. Problem only occurs when accelerating from low revs (eg approx 1500 revs). Engine falters and check engine light starts to flash. Sometimes it goes out and sometimes it stays on. If you stop and turn the engine off you can sometimes get it to go out. My scanner shows a 29CC (misfire on cylinder 1) and 29CD (misfire on many cylinders). Signs of oiling on both spark plug and injector. Have swapped plugs, coils and injectors but codes stay the same. Have done a compression test and a leak down test but cylinder 1 results normal. I have used INPA and the readings on cylinder 1 seem normal. I can drive the car and avoid the fault if I keep the revs up (above 2000 revs) by using manual mode. Cars idles well but sometimes hiccups after running for a couple of minutes but does not generate error. Seems to be more susceptible when cold. Local indie thinks it is eccentric shafts and/or intermediate levers but I think he may be being influenced by reported faults in earlier models. Don’t think he is interested in proceeding to fix the problem. He has told me he thinks the parts alone would cost about $8500.
I will try Clickable for eccentric shafts just in case. Have had difficulty finding them. Lithuania and US sometimes have them for about $1500 each.
