Is your MAF good? The blow test - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I know my z32 used MAF is responsive, because the signal wire generates 1V when I blow through the MAF.

Is it possible it is still bad? I am getting terrible idle and don't find any leaks.

^ I don't remember what mine read but I wouldn't think its the culprit if it is responding to air flow. Have you recently messed with your coolant system? If an air pocket is created in the IACV an SR20, which I'm assuming this is, will idle terribly. IIRC the motor should idle without the MAFS hooked up but can't be revved above 2k RPM.

clean out the sensor inside the maf if its dirty it wont get u accurate readings. Use mass air flow sensor cleaner when doing so
