rb20 idling high (ANNOYING)

[siedway]

Help me before i pop the living out of my clutch and drift straight into a police car!! Alright sl i have an rb20. Basic bolt ons. Fmic, full exhaust walbaro 255, a/f gauge reads a pretty steady 14.8. I have a safc II but ij how to use it. Cwr doesnt run rich or lean. Everything is fine other than my idling problem

Sometimes i start my car and it idles at 2k. Sometimes itll go down to 1.2-4 or itll go higher to 3 (less likely) it gets on my nerves. Once in a while when its running fine idle at 1.2 k ish and i come to a stop itll want to die after a few secs so i tap gas once and its fine. Whb it is acting dumb and idling at 2k ill put it into 5th and bring down rpms to 1k but itll climb to around 1.4k

Damnit wtf is wrong D:<
