so i installed my o/r x today with mils (which were both used), drove it for about 1 1/2 hours and no light. so i took it out again tonight, and about 20 minutes into my cruise the service engine light came on. i'm going to double check the o2 connections in the morning, but is there anything else i should do to make to make the light go out? i know the car runs rich when the lights on, so i would like to take care of that asap. thanks

probably bad mils.. i would take it and get tuned, what brand mils did u get? also go to autozone for free and get the codes read and erased

The mils are more than likely the problem. Stop at autozone and have themcheck the code it`s throwingjust to make sure.

i don't know what brand because they came on the x but i will check tomorrow. if the mil's are bad will there be a different code other than rear o2? and is there any other possibilities other than bad mil's?

^iLLuSiOn^

um depends on what the code says, but yes if its the mils it will say rear o2 bank 1 or bank 2

ok i'll get the codes read tomorrow, but if i have to order new mils what should i go with. i just did some searching and found them everywhere from 30-80 bucks??? is there any real difference?
