Hi there, My engine has the LH bank injectors permanently open as soon as ignition is on (as you can imagine this is quite dangerous). I have disconnected the lambda sensors (no change) when tracing back the signal to open them it is shown at the emu and is permanently present on the pins going to LH injectors. When I change the emu the new unit is the same!!! Any ideas where to go now??
What sensor is only for the LH bank injector signals apart from the Lambda and, can be giving this problem?

All help is gratefully received
