is this a 4 or 6 cylinder?
if a 4 cylinder it will only have 2 o2 sensors
V6 will have 4 o2 senors which the sensor will be the right side of the engine first sensor.
1st sensor on exhaust, I recommend if you change one change all, as this will make the computer when it rechecks the system you have all clean/fast responding sensors.
if you have a slow response it means the sensor is dirty and not reading well, which is usually caused by minor misfires that the engine computer dismisses, so a tune up would be recommended too.

What you do, is take it to a shop and you drive and have someone ride with you to diagnose the issue. You never leave a veh at a shop with out a road test and a mech or tech that has some interest in finding the problems. Also run it on the lift in the shop to see if it can be duplicated. Preferablely on rollers on the ground, such as a dyno machine,, so as not to harm the drive axles, if that applies to your veh.

Testimonial: "Thx! May do. Can't spend $$$ on "sometimes". Thot it might be a belt, but car revved in neutral--no noise. Got to be a moving part somewhere."
we have a 2003 saturn vue which we installed new tires on and we noticed a noise about 6 months afterwards. it sounded to my wife and i to be loud road noise from the tires. the car was driven for 6 months and we decided the noise was annoing. had the tires checked only to find it was the left front wheel bearing which was replaced and stopped the noise.

If you have no leaks dont worry about it. Just get it serviced if its time. Alot of cars are this way now. You need to be under the car to drain and fill. My BMW is this way
