When i bought the back in 2007 i was told that it was an easy fix to just change the o 2 sensor out of the car and all will be fine well i had the car hooked up to a computer it said bank 2 sensor 1 the car come to find out has 4 of them 2 on each side so we change bank 2 the check engine light went off but came back on with in 10 minutes so we decided to have all changed just in case but now it has been over 3 years I've taken to 3 different mechanics and they all say Isuzu are hard to work on that it is all electrical and that have issues well i don't have money to buy a new car so i guess i stuck with this one by the way the real reason it make me mad about the sensor is because my car drinks a sh*t load of gas now it was suppose to get at leat on highway 28 mile per gallons I'm lucky if i get 20 on highway and about 15 in town it about the same as driving a damn hummer.
