Cel P0505

I received a pending CEL p0505 Idle System Malfunction, diagnosed and replaced IACV with a Brand new OEM unit. Also replaced the Bypass Thermal Valve, this is a California car so I can’t just delete the Thermal valve. Can’t get rid of this CEL, car idles around 900. Can’t figure out why the motor make this bubbling noise. Currently bleeding the coolant, front of the car is jacked up all the way & using a funnel, any help?
