Sounds typical of head gasket failure.
With this you get oil into cylinders / water into cylinders, burning oil, loosing water - but no leaks. "boiling" of radiator and overflows.
Check your coolant and oil levels - they will be low.
Get a few quotes for a head gasket replacement - and timing belt change, as it has to come off when you do this anyway & no sense putting an old one on - they often snap if retensioned.
If this solves your problem, please take a moment to rate as Fixya! thanks.

SOURCE: Electronic Throttle Control
Throttle actuator control system-forced limited power
• The PCM monitors the throttle actuator control current when the ignition switch is on. If the control current is less than 8 A or more than 11 A, the PCM determines that the throttle actuator control system is under forced limited power. Diagnostic support note
• This is a continuous monitor (CCM). • The MIL illuminates if the PCM detects the above malfunction condition in the first drive cycle. • PENDING CODE is available if the PCM detects the above malfunction condition. • FREEZE FRAME DATA is available. • The DTC is stored in the PCM memory. POSSIBLE CAUSE
• Throttle actuator malfunction • Connector or terminal malfunction • Open circuit in wiring harness between throttle body terminal A and PCM terminal 1B • Short to power supply in wiring harness between throttle body terminal A and PCM terminal 1B • Short to GND in wiring harness between throttle body terminal A and PCM terminal 1B • Open circuit in wiring harness between throttle body terminal B and PCM terminal 1C • Short to power supply in wiring harness between throttle body terminal B and PCM terminal 1C • Short to GND in wiring harness between throttle body terminal B and PCM terminal 1C • PCM malfunction
and for the other one
the dealers need to reflash the powertrain module ( ETC ) ...
hope i'll not get that problem on my 04 hemi...

The 4x4 is controlled by vacuum. There is a vacuum switch on the top of your transfer case that control the vacuum to the front axle shift motor. The shift motor has 2 ports, when vacuum is applied to one side the shift motor moves the fork one way and when vacuum is applied to the other side, the fork moves the other way.
The first thing I would do is verify the hoses at the transmission cross member are hooked up. Then I would remove the 4 bolts from the shift motor and remove the motor and start the engine and shift in and out of 4x4 waiting 10 seconds before each shift and see if the fork moves.
If it doesn't you will need to check the vacuum connector on top of the transfer case and make sure it is fully attached, if it is, you will need to remove the vacuum connector and check to see if you have engine vacuum on one port(around 15" vacuum). The ports are as follows - one port goes to engine vacuum, one port goes to a vent and the other two go to your shift motor. The hoses that go to the shift motor are bad for getting plugged, so you should use compressed air and see if they are clear.
If everything checks out, you will have to remove the switch on the transfer case and operate it by hand while the engine is running and see if the plunger moves in and out. Sometimes the plungers will stick in!
A vacuum gauge and pump are needed to check the motor and switch. If you don't have one, you might need to borrow one and put a vacuum on the shift motor and see if it holds vacuum. Once you put a vacuum on the shift motor the fork should move and then should pump down and hold a vacuum, if it doesn't hold vacuum, you will need a shift motor.
This is alot of info, but there are many possibilities for this not working and you will have to check all these things to diagnose this.
