Winter cold starts should be a lot easier to dial in now that your IAC effective area table is in better shape.
When you log this update... start logging before you start the engine so I can see the engine start-up in the log.

Latest log. Looks like the IAC is going to zero steps again. Don't know why it would do that on this log. Nothing else has changed. I don't know if i can close it much more than it is.
there's now too much physical air causing the PCM to drive IAC all the way down to zero (i.e. and now PCM can't reduce/control the amount of air)...
Your idle trims are very consistent now... which makes me think that your IAC valve has just lost its way. Try doing an IAC reset.Originally Posted by spy2520
Good point.
Hmm I'll give that a shot.
