Hello Friends,

I have a problem with my Alfa 147 3.2 GTA


There is a problem of sensor lambda (O2 oxygen sensor), I replaced the sensor with a new one but the problem is always present.
There is an error with FES, the engine has misfires (spool and new spark plugs)


Can you disable the O2 oxygen sensor for the engine to run normally?


Thanks for your help

Lambda 1 pre-cat compared to the lambda signal 2 pre-cat the work is not good.
You must first of all check to this sensor.

I have already replaced lambda 1 after catalyst, diagnosis with multicuscan say error lambda 1 after catalyst. For you I need replace lambda 1 before catalys?


thanks

Yes its characteristics of the waveform is too flat in relation to the lambda 2(red color) it looks miserably

I have replaced the sensor 1 before the catalyst but the problem is the same.
There are misfires when the engine is idling.


There is no OBD error code
Lambda sensor graphic is ok.


Do you have an idea?

Are there misfires in the suction manifold or exhaust manifold?

Sorry!
That question it is my mistake because my English is not very well.
You try cleaning the injectors and check the engine timing.
