The O2 Sensors in my car have to be replaced. If i just put MIL eliminators on the back ones (possibly good i'm not sure) will it work? I'm trying to save some money cause I'm a little short on the green stuff right now.

 

They trick the computer into thinking there is a correct reading if you get rid of the cats...so in theory it should trick the car with cats too

 

Yes it would work.

 

cool, that will save me like $100. Thanks for the info!

 

How do you know it's the rears fowling out?
