Hey guys, whats up? I've notice that my gas mileage has gone down alittle. I just had new tires put on, balanced and all that, i was wondering how long before we need to replace the o2 sensors. i know if that they become fouled, they become lazy and use fuel than needed. Any info will be appreciated. John

 

unless you have like 100k miles or are running leaded gas on a regular basis they should be fine. if they go bad they throw a code too. check your tire pressure and your driving habits. lay off the boost some lol

 

I agree, they install those things to last a loooooooooong time. Trying to replace or remove one is a pain.

yeah i agree.. i think that u are probably boosting high.. got a boost controller?? set ur boost real low when u are just driving to work, etc.. but when u racing or whatever crank it up..

 

along with checking pressure and yourself, when was the last time you checked your plugs as well? this car is known to eat them.

 

thanks for all of the advice. Think the problem might be my right foot. lol
