Confussed high idle
Well would like to ask something I find odd... on a cold morning I start the truck....(fires right up) and settles into a normal idle(around 650-700) after its Running for 30-40 seconds the high idle kicks in(1100).....Is this normal is it supposed to warm a bit before it goes to high idle....thanks again...

Yes.
The cold-weather warm-up strategy only works when the oil temp is below 40 degrees or so.
The high-idle mod gets your engine RPMS up for whatever reason you choose; and extended idle-time (especially without daily "blow-outs") is damaging to the engine.
