brandon18 Posted March 20, 2010 Share Posted March 20, 2010 I have a 2000 Honda Civic that recently had a OE engine swap due to the original engine locking up. The car idles really odd so I took it to a local checkers and ran a test. Found code PO505 came up so I took it back to the shop and they place my original IAC ( Idle Air Control). Seem to be good when I left but later on that night started to idle really rough again. I was wondering what else I can look into to resolve the issue with the idle so I can get my car finally back, I was told to clean the mass air flow sensor, could this resolve it?? Any suggestions would help out alot. Thanks, Brandon Quote Link to comment Share on other sites More sharing options...
