2001 dodge ram 1500 5.9. I have 159k miles on the truck. It is not throwing codes but should I change out the pre cat o2 sensor. Or not waste the money.
It probably wouldn't hurt....although if you havent had a tune up recently then that money would probably be better spent there. I guess the 02 sensors are considered by some to be tune-up items but i was thinking more plugs, wires, etc...
