Idle Issues
On cold starts my idle bounces up and down between 1000-2500RPM and will sometimes stall out if I'm not steady on the gas. Problem goes away after the car is warm though.

The engine is an S13 blacktop, Z32 MAF, Blitz atmospheric BOV (I know I need to recirculate).

I was having issues with stalling after high boost due to the BOV, so increased the idle using the screw at the IACV.

I'm thinking TPS or temperature sensor. The thermostat is new.

Any ideas?
