Below is on a 98Z28 A4.

Today I played with this table in an effort to correct a warm starting problem and it seemed to work okay. But…
The problem is that when you transition from park to drive or drive to park it seems that the values in {B4343} Startup Friction Airflow Correction table are also added to the {B4703} Desired Airflow table and the IAC counts jump up and as expected the idle increases.
I thought that the values in {B4343} were only applied at startup and for a very short time afterwards as controlled in the {B4344} Startup Friction Airflow Decay and {B4345} Startup Friction Airflow Delay tables.


Does anyone have any experience with the idle start-up tables?

Thanks

John
