Problem with gas fumes
«

My G40 can not pas the gas testing at 2500rpm (it's runing rich) but in idle is great... First of all i've changed the blue temp sensor and i cleaned the injectors...
Is there a possibility 1) The lamda sond is broken?
2)Fuel pressure regulator broken?
3)Co sensor broken?
4)MAP senor?
5)Problem in ECU?
Do you have any idea what may be wrong???

sorry - probably the case, the problem. (mistyped)
lambda probe can be seen working with an air fuel ratio meter

I've checked with gas analyzer and the λ seems not to be steady at measures (it's going up and down, from 1.06 to 0.963)

Then the lambda seems ok.
It goes up and down around the lambda=1.00 value.
So, lambda value is ok, but CO isn't?
Did you check for air leaks around the inlet manifold?

yes it is... with a multimeter and by setting the screw on top (it may be under a blue cap)
