hey evildky thanks for your reply i replaced my mas not to long ago you think it's going bad again? it only stumbles once in a grat while .should i chek my ecu codes?

checking codes is always a good start

the rpm dependent issue on an older Z would point to the AFM, the Z31 however uses the MAS, not sure if it can present in the same manner

might be worth having a look at your plugs and wires, could be loosing spark or arcing out
