Thanks, for the DAG info.
I would have thought that the IAC motor could have taken care of slight leakage. Most cars have an rpm swing at idle as the sensors give info back to the ECM in a negative feedback fashion.
Perhaps this is because of the Speed Density system and/or the slower talkback rate of the OBD1 system?
