Ok,guys my y pipe is coming soon so i was thinking i should go ahead and get an oxygen sensor,cause i haven't changed in the 2 yrs. i have had the car. oh yeah i just hit 140k, and i think my gas mileage could do better. tune up was done at 100k, fuel filter, spark plugs, timing check. Now, i know it should have been changed then, at the time i didn't.

 

Yeah I would if I had the money to.It is supposed to be changed like every 60,000 miles.
