OK so my Z22se is finally in and running in my Zafira but I have abit of a running issue which I am hoping you guys might be able to help with, sometimes, not always, it stalls as I come to a junction, it will restart straight away, if I catch it from stalling it will run on 3 cylinders for a min or so and then clear and go back to running fine, this only happens at low RPMs and if I drive kicking its head in its totally fine, these issues only seem to happen below 2k rpm, could this be caused because I am having to temp run with no second Lambda????
