It's possible that you have more than one issue with the car.

First up, is there a "Check Engine" light showing at any time? How about an ABS light? Do your brake lights come on? Can you engage cruise control and disengage it with brake and/or clutch?

If there's neither light, it could be the SCV causing the limit to your revs, and it might just be a brake or clutch switch stopping you engaging 4WD. Does it enter 4HI ok, and just won't enter 4LO or is it any 4WD that can't be engaged? This might be a problem with the servo in the transfer case, or maybe even just a relay in the engine bay.

Let's start there.

If the ABS light is on, check your front wheel bearings. Two ways:

* Jack the wheel up and shake the bejeezus out of it. It shouldn't budge except for rotation.
* Take the car for a drive and listen. On a corner where you can maintain a steady pace in both directions, listen for louder sound - if it's louder when taking a left hand corner, your right hand wheel bearing is toast (and vice versa).
