Z32 MAF issue

alrighty guys,

quick and simple question

Z32/SAFC car was tuned idled fine then. fast forward to now.

car runs great under load, just wont idle for crap, if i disconnect MAF idles right at 1000rpm if i connect jumps around like a vac leak then dies
ive triple checked all vaccum lines, IC piping and couplers and nada.

could it still be a bad MAF even though the car runs fine under boost and load?

It could be... I think the FSM has a way to check the maf resistance to see if it is good..... I could be wrong but try it....

but yes it could run ok under load, but die because of the lower threshold metering..... also check if any of the leads on the sensor is jacked....
