Is your Z32 wired in correctly? Is it earthed properly? Did the car work fine on a standard MAF with the same map? If all answers are yes then there's a good chance your Z32 MAF is damaged.

the wire was correct fitted. with the standart maf it runs ok. so i believe that is really damaged...

Can you see what voltage is reading at idle?

 

[Thor]

yes i can see. but which values it must have at which rpm?? so when i switch the ignition on (the engine does not start) the value is sometimes 480mv, 690mv or 780mv.
