I have a check engine light. I put a computer on it and the code was P0507. The definition was the Idle Air Control circuit or idle speed higher/lower then expected. Explanation was that the ECM has detected that the IAC counts are higher or lower then expected. The engine speed is not it's expected range. The four probable causes were vacuum leak, dirty throttle body, IAC motor defective, or poor electrical connection to the IAC valve. Is there anything you can tell me about this. How much does it generally cost to fix? Is this a common problem for this year and make vehicle? Etc. Etc. Thank you.
have the same problem?
