Hi! I have a P0505 error code and my 1999 automatic honda crv has been stalling a lot. Uphill, downhill, I have cleaned the IACV, throttle body, bled the coolant and refilled with new coolant...not sure what else to do but check for a vacuum leak. It was stalling for about a month before the check engine light came on. Any suggestions?
That code is for the idle speed control valve. Please follow the link P0505 Honda Idle Air Control Valve

Get a can of carburetor cleaner and spray it into the throttle body while the car is running.

Any cleaning or modification in air fuel mixture valves/ and sensors can modify their function which could trigger a false read on the ECU in the car. You will likely need to have someone with a code reader plug in under dash to reset the lights and give you a readout

P0505: Idle Air Control System
There is a small motor that controls the amount of air the engine gets when you aren't using the throttle. The computer uses this small motor to control your idle. It sounds like it needs to be replaced. You can try cleaning it first with some throttle body & air intake cleaner.

After the IAC is replaced it is not enough to clear the code you must also reset the IAC learned adaptive. To do this you will need a higher end scanner like snap-on or such.
