Im sure my o2 sensors are bad, i got the code at shucks and im about to replace them, one thing i was woundering, can anyone tell me the part number? or numbers? for the two o2 sensors? im sorry i didnt have time to search but i need the answer fast, so thats why i was asking, also, anyone know how hard they are to replace? i can see them from under the hood but dont know the difficulty level... and once the new ones are in how do you go about clearing the check engine light? and is there anyway to tell which one is bad? thanks in advance
