Negative, still happens for about 3-4 minutes after startup, once warm idles were it should... Really makes cold parking lot maneuvers and the neighbors mad... On a stock ROM the car doesn't high idle when cold.

Are you using stock or modified iscv settings? Are you throwing ending codes? What are your isc steps at idle?

Also what is your ignition timing set too? I have mine set to about 11 degrees with gsc s1 cams with a slight lope around 1000 rpms no surging. Is your idle surging up and down or just constantly high?

Every value is stock except wot timing and Afr, injector latency.... After 5 minutes the car idles perfect at the value it is set for (1k), it doesn't surge it just shoots up to 2k on start up.
