The 4x4 light stays on and on sharp turns feels like it is braking. Any ideas?

3 answers to this question. The car is running lean and the problem is caused by: 1) bad co2 sensor. 2) the fuel filter is stopped up and you need to change it along with the air filter.3) a tune up is in order. Those would be the main 3 reasons for the car to act in this manner. Code reader should help lead you in the right direction.
