Hey everyone my truck (1999 Ford Ranger XLT 4.0) has been acting up. When i start it sometimes it will die on me, when i accelerate it like to jump and jerk. I talked to my girlfriends dad who is like a beast when it comes to cars, and trucks and he said it sounds like the O2 sensors is tripped. He told me there is four of them located on my truck. Do any of you know where they are located?!?!
