check engine light, tied to 4WD use?

Greetings eveyone, I'd appreciate advice on the following:
Most times after I engage/disengage from 4WD the 'Check Engine' light comes on and the car hesitates, mis-fires (as if the timing were off or the gas were dirty). By accident I found that turning off the engine and re-starting it most time solves the problem -as the engine seems to go back to normal and the pesky light goes off.
How do I solve the above for good?

Thanks,

Thanks. The possible causes you describe, are those easy fixes?
The question has to do with the fact that I keep my trusty '93 YJ in Mexico for when I am there: although there are competent mechanics there they don't necessarily have access to the wealth of information we have here at home.

Have a great weekend
