Be careful there.. If you remove the Throttle Position Sensor TPS or the throttle Cable, the engine light will come on because there is a certain setting that needs to be done to ensure accurate emission control.

check oil level in transfer box first.this car is designed to come out of 4wd at around 21mph on its own. you may need to get electronic diagnostic machine check..

if the problem immediately followed the cable being disconnected, its probably out of adjustment. if the cable is too slack, it won't be able to open throttle enough. if its too tight, it will hold the throttle open. should be able to loosen the adjuster nuts and tighten up the cable

The Engine and Automatic Transmission (not applicable to manual transmissions) in this vehicles drive train are fully electronically controlled by a computer called the PCM and TCM (Power Train Control Module, Transmission Control Module). When a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM. Also always check fuel pressure for correct spec for your make and engine type.

Remove the accelerator and cruise control cables.
Remove the engine coolant hose and throttle body.
Remove the P.C.V. hose and brake booster vacuum hoses.
Disconnect the vacuum hose connections.
6. Remove the surge tank stay.
Bleed off the pressure in the fuel pipe line to prevent the fuel from spilling & squirting you in the eye.
Disconnect the connector from high pressure hose.
9. Remove the surge tank and gasket...be careful with gasket, you can reuse it.
11. Remove the delivery pipe with the fuel injector and the pressure regulator....
When the delivery pipe is removed, be careful not to drop an injector.
Disconnect the wiring harness of the coolant sensor assembly.
Remove the surge tank.
Ignition coils and ignition wires:
disconnect ignition coil harness connectors
disconnect ignition wires from ignition coils
remove hold down bolts from ignition coils
while gently twisting pull up and remove ignition coils
while gently twisting pull up and remove ignition wires
remove spark plugs (always check gap on new plugs, even if they say they are "pre-gapped" )
Install in reverse order, don't over torque anything and keep your work area clean. Now would be a good time for wire replacement too---depending on the mileage on your Kia
Do a good visual inspection of hoses, clamps, wires & pulleys while you have it "opened up" ---Good luck, thanks for using fixya and i hope you get many more trouble free miles out of your Sorento. =)
