I fought a idle drop an a very rare stall for maybe a year until I found a discussion like tis here at the nation.
Went to the dealer with a list of PCM updates, one of which was for idle. That morning, with the truck warmed up, it would drop to 400 +/- rpms then settle back to just about 600rpm. When the update was done, I would settle to 675-690 rpm per my Scan Gauge.
Just looked at my work order, this is what the note says for the idle update:
"install available updates for PCM Program Code 1061F"
I'm assuming the PC 1061F was an update name or an address inside the PCM.
