  1. It is possible. You have a fairly major issue there, the exact problem would have to be diagnosed but I’d say you have a fairly major air/fuel ratio problem. Your lambda is 0.67, which means no air going in to system properly, so could be leaking air hose, dirty – never changed air filter or faulty air flow sensor.
