Hi, first time poster here... we recently got a Picoscope 4 channel kit and I have been trying to get to grips with it... We have a Vauxhall Astra 1.4 EcoTec 2002 model in the workshop with high CO. readings are CO 0.8, HC 130, o2 1.8%, Lambda 1.02 No DTCs present on vehicle. No misfire, car runs ok...
