so the check engine light comes on and i stop at autozone to "borrow" their tester and it tells me that i have an O2 sensor going out.
-- no big deal, i think --
off i go to the stealership (because my sensor is not available otherwise -- 2001 w/ 4.0L) thinking that this will be a quick, easy cheap job. HA !! there are 4 of the stupid things, all with different parts numbers and the cheapest one costs over $100.
is there any way for me to tell which one of the four is going out so that i can only buy the one that i need ???
