It depends whether you have 4 cylunder or 6. If a 4, you have two O2 sensors. One in front by the manifold one on the back by the catalytic converter. the 6 cylinder has one more in front. You need to go to a shop and have them plug in a diagnostic reader to see which one is bad before you go and fix them. Usually diagnostic is around 40 dollars, the sensors anre around 100 each. usually one hout r labor.
