What's the deal with this Honda ?!?
I've cleaned the throttle body out numerous times idle went down to just under a grand sometimes idling it will bump up and down to 1500 RPM. It never stays that high.
But I keep getting a p507 error code for the IAC valve. To which I replaced for 200$ plugs wires new filters and the code still persistently comes up. What could this be?
Possibly the only thing I have not changed the fuel pump?! Changed the gas cap as well I'm at a loss!

Beyond frustrated please help. I need this car to last me till tax time and she's due for an inspection in October. She runs great but that codes unsettling.
Any help or advice is beyond appreciated.

 

Likely needs idle relearn done.
