Over fueling issue

[Sx-mad]

Hi from a newbie

Hey guys I'm currently having an issue.

My car run fine a couple of weeks ago and all of a sudden my alarm had stopped working meaning my car was permanently imobbilised.
So I get the snips out and bypass the immobiliser and get the car started but my new issue is the car is overfueling.
The only thing I have found so far is that my afm voltage on idle at 1000rpm is 1.6-1.7volts when warmed up.

Spec is

Power fc
Z32 afm
740 injectors
Apexi filter
Apexi gt spec exhaust
Nismo fpr

Any help would be much appreciated

Thanks mark

How do you know if the car is overfuelling?
What symptoms do you have that lead you to that diagnosis?
Do the symptoms occur the whole time that the car is running, or do they only happen sporadically?
Going to need a bit more info about the issue(s) to be able to help out.
