Better news. Sorting out lambda connectors and new spark plugs seems to have worked. Though I can't take it on any prolonged test due to road salt, and I haven't had it on the app yet. However, today, from left hand exhaust (would that be right for front three cylinders?), figures were - fast idle CO 0.03%, HC 3ppm and lambda 1.03. Natural idle test - CO 0.02%. Cleaner than the bodywork!
