Gets better on warm up.
With engine running on three cylinders, if it is switched off and restarted, misfire is cured.
Re-check, DTC all back.
Checked gases when hot at idleCO 0.01%HC 1ppmCO2 14.09% O2 0.09%Lambda 1.00%
Rev engine and Lamda goes weak to about 1.56 and air mass goes to 156 Kg/h.
Any comments on these figures please, Otherwise I will try a Maff sensor.
Thanks Ian.
