Sometimes when I start the car cold, the rpm would idle between 1k to 2k for several seconds and it’ll idle normally after. Is this normal? I’ve cleaned my IACV and bled the coolant and that fixed the other idle problem I had when stopped at a red light. Any tips are appreciated

 

Be sure to clean your throttle body and air passages. Idle surge is normal to some extent on a cold start as the car adjusts to air temperature readings. Front oxygen sensor readings can also effect idle
