>From the alt.autos.dodge.trucks groups comes this interesting news:
<copied and edited slightly>
The TSB is #18-023-00, Rev. A. It applies
to '00 (AN) Dakota, (DN) Durango and '99-'00 (WJ) Grand Cherokee
equipped with 4.7L Federal Emissions (Code NAA) engines.
It will address the following symptoms:
1.) Part throttle or wide-open throttle spark knock
2.) Sag or hesitation following a cold engine start
3.) Rough idle
4.) Idle sag on deceleration to a stop
The TSB involves reprogramming your PCM with new software (99Cal20 and
00Cal17)

I am hoping this fixes the idle variation I've been experiencing. It's back
after the dealer replaced the IAC.
I also have to get the TSB done for noise in the rear leaf springs.
And I have to get the truck in for paint after the overhead door at work
dropped on the ARE cap.
