Ehh it could be a lot of things. I know the JDM engines run rich when there first started. Do you have any codes? Check your O2 Sensor

^ya thats what ive read and mine does untill its warmed up it idles/runs perfect. Your base fuel pressure might be too low at idle causing the ecu to dump more fuel. Top end wise tho it will be lean. Again thats just fuel pressure related. Whats yours at?
