Lambda at 25 - should be 42 (84 380SE Fuel Consumption)
I have been griping about the high fuel consumption in my 84 380 SE for a long time. So I finally broke down, took it to the stealership and allowed him 1 hr to tell me why.
This is what he says, I quote "your lambda is 25 while the spec is 42. We cannot crank it up any higher . We do not know why - could be the fuel rails or the injectors".
I wanted to ask you all what this means ? Should I replace injectors ? Or replace the cold start valve ?
