RB25 Idle problem! - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Mine was doing this but I cheated the IACV. There should be a small adjustment screw on the TB that would crack the butterfly just enough for it to have a stable idle.

Make sure your maf is at leasts 12 inches from the turbo,and that there is a major bend in the piping. Ran into the same problem

Yeah I've messed with the screw but no matter what, it will idle up and down. It will find steady idle if I open it up all the way but it stays idling at high rpm

Yeah the maf is 12 inch from the turbo with a 90degree bend
