I love that Check Engine Light--Codes

Damn CEL came on so I hooked up the logger and came up with two codes

P0505-Idle contol system malfuction. Would a bad ISC cause this code? Cause my idle is funky and its not the EGR,BISS, cleaned TB..only thing I haven't done was leak tested.

Also got:

P1400-Manifold Differential Pressure sensor. What would cause this error?

Not sure if this applies to DSM's, but IAC(Idle Air Control) valve??

Happened on my Civic. Same code. It would idle real wierd too.
