P1507 and P0505 after cleaning IAC...

mc2 · 04-13-2009, 11:41 PM

So I had to take my IAC off when i was pulling my tranny to get access to the service hole.

I took the liberty to clean it off with q-tips and rubbing alcohol while it was off.

Now when i start the car up the idle is at around 1200 when warm and the suddenly the CEL came on and idle dropped to about 800-900 but it was a very rought idle. The two codes that came up are: P0505 and P1507. Apparently both related to IAC.

I didn't change the gasket, but on the older EJ22s its not a rubber gasket, but instead some type of composite material.

I also sprayed throttle body cleaner all around the IAC and vacuum hoses in that area, I couldn't detect any changes in idle. I don't believe that I have a vacuum leak.

Any ideas? is it possible that i screwed up the IAC trying to make it better by cleaning it... Car was running fine prior to tranny pull and reinstallation.
