Hippocampus s7 cold car idling one big and one small.
Bad job.
The idle motor is not working well and needs to be replaced. Either the throttle is dirty or the air flow meter signal is unreliable.
I suggest you go to the 4S shop for maintenance or ask a special maintenance person to do it. You can't do it yourself, or your car may be scrapped. You'd better check it.
