Idle is controlled solely by the ECM/PCM there is NO IDLE ADJUSTMENT.

800-850 RPM's is typical...

The only thing I can suggest is try doing a APPS reset... There is a phyiscal reset for the APPS too you might try as well...:w:

you can pull the APPS plastic cover off and drill out the idle screw and re-tap it and play with it but it may mess up the ECM/PCM......i have heard of a few guys doing it.....i have never tried it my-self

Are ya sure its not a u-joint/backlash issue? just for fun put it in 4X4 and slip it in an out of gear.... mine bangs as well but in 4x4 it slides in nice, mine has play in the rear slip joint hence the "bang"

when in 4x4 it helps to take the slop out of the driveline, unless the front shaft/u-joints is shot, also if the rear brakes are out of adjustment it too can account for driveline bang
