    hi any one experienced emission problems with these basically it has a lambda code stored for intermitant performace. tests show lambda at 1.15 smoke tested every thing and seems ok although by ear you would say it has air ingress.however o2 senser through serial shows 0 volts although sometimes at ecu plug with scope it can read o,2 volts. so you would say it is very lean, now if you increase revs to run cat test the co will go to around 9/10 percent .injector duration = 2,5ms and o2 senser does not realy change ie 450 mv . if i induce 1 volt to signal wire ecu reads 1 volt but still runs at 2,5ms.the ecu and lambda has had some oil ingress and i have checked all supplies and earths etc ECU ?
