:rev to 2500? or are they both acting the same? If they are acting the same then of course its something other then the MAF unit its self. Could be the circuits to the MAF or anouther component and/or system altogether. Maybe you could try your MAF on his car and see if his runs properly, then its Definetly not your MAF unit its self. :Do you have a SAFC? if so go to sensor ckeck mode and read the value of the voltage, this can help diagnos if you have a short or open to the MAF sig
thanks 4 the tip..i tried my mafs on my brothers z and it had code 21 so i'm sure my mafs is dead...i tried his mafs on mine for the second time and wolla..it works...sorry for the trouble guys as i'm new to the z32....i guess it is true that all 90-96 Z mafs were interchangeable
