If you had the battery off for a bit, I know Yas has been doing a bit of work so you may done as well, then you reset the ECU, mine always runs a bit high for a while after its been reset, soon settles down once you have done a couple of runs and its learnt a bit. I would explain it better but gotta go out, that the basics tho.

Check the throttle sensor mate cause if it's not wotking correctly then your Z will always idle above 1000Rpm
