It means check your O2 sensor. Down there screwed into your B-Pipe on your exhaust. Take it out and borrow a friends if you can to check it real quick.

it should look something like the pic above. if the o2 sensor is replaced and still doesn't help, try adjusting the FITV, usually beneath the throttle body. My b16a would cold start at 2k, but after fixing it, it's at 1.5k.

 

check intake air temperature sensor..mines idling up at 2k and wont go and changed that..fixed it
