High RPM Cold Start P/N

[Protec]

Hey gents -

I've looked around the site, tutorials the Internet and such and can't seem to get pointed in the correct direction.

I have a 6.2L L9H Truck Motor with 6L80E in a Jeep. I'm having a cold start high rpm spike in park that sends the RPM's to 2K and then it quickly tapers back down to the desired idle as programmed.

Can this be corrected in the "Airflow Correction Coolant Multiplier" or am I way off? The only other mention I found was with regard to the "Idle stepper motor parked", but I don't see that in my OS.

Any help getting me moving into the correct tables would be greatly appreciated.


Best regards,

John~

I'm not sure if that table will do it...

joecar...

Thanks for putting them in one place. I've been reading hundreds of pages and it looks like it will not be a simple single area fix... I just need to dive in and start making some changes and that's the best way to learn.

Very much appreciated,

John-
