SOURCE: clouds of white smoke
Dense white smoke usually indicates coolant/antifreeze getting into the combustion chambers. This can be from a "blown" head gasket or from a crack in the cylinder head or the block. In either case, this involves some major work on the engine. Replacing a head gasket is preferable cost-wise to replacing a cylinder head or the entire engine (block).

It could be a coolant or transmission fluid leak in the combustion chamber. Check your coolant and transmission fluid to see if one or both are low. White smoke from the exhaust is a classic symptom of a blown head gasket, have your cooling system pressure checked. If that checks out good then have your transmission checked.

If the engine is using oil then first remove the dipstick and run the engine, check to see if heavy smoke is coming out of the tube, this would indicate worn piston rings,if it is not so dense, yet you are using oil and it smokes bad from the exhaust, then its likely the valve seals are worn. either way, unless you have mechanical knowledge, tools etc , you need to take it to a mechanic for the engine repairs or live with the oil consumption. There are no quick fixes for engine wear.

SOURCE: My truck is blowing white
white smoke means there is a presence of water/coolant at your combustion chamber. common cause of this is blown head gasket and/or small cracks/holes in your cylinder head. if this happens, water will not circulate properly in your engine thus the vehicle will shutdown due to over heating.
what to do:
1. replace head gasket. this is quite not a DYI fix since it will require some tools like torque wrenches and some knowledge on timing.
2. if replacing the head gasket does not solve your problem, have your cylinder head resurfaced at the nearest car service center. resurfacing makes sure that your cylinder head perfectly fits with the crank case.

SOURCE: Idle is high at start
white smoke out of the exhaust would be a sign that it is burning coolant... if it goes away after it warms up, it could just be condensation inside the exhaust pipe. 1800 rpm is a very high idle, maybe have your IAC motor on the throttle body checked... check engine light? if so have the code read at your local auto zone.
