The HO2 sensors + plugs should last 100k miles

danielsatur,

Let's hope it not the fuel filter cuz it located in the tank!!!! OK the o2 sensors may not have to do with the issue/problem cuz they last 100K BUT my spark plugs are always changed when it's time for a tune-up as per the schedule. I think/believe they use Champion.
