Oxygen Sensor

I have a 1996 Saturn SL. The engine lights comes on and then starts to
flash. It feels like the motor is boggin down. I took it Autozone and they
hooked it up to the little computer thingy and told me I needed to replace
the oxygen sensor. I did, and it hasnt helped. I bought Bosch oxygen
sensor. Any ideas?

Yup, find the root cause not the symptom. Only get codes from autozone,
not advice. They sell parts, not fixes.

What is the service history of your car? Have you kept up with fuel
filters, plugs, wires, and the like? Your O2 sensor is looking at air
fuel mixtures. Start looking at things that effect that.

well come to think about it, could the exhaust have something to do with
it. My husband had a buddy of his to do something last year to make it
louder, well ever since then, when letting off the gas, it pops.. What do
u think? I have no idea about cars and stuff like that. I guess it prob
needs spark plugs/wires and the whole nine yards but there is definetly a
problem somewhere..

I totally missed this post. 2 things come to mind for exhaust related,
not enough back pressure and/or an exhaust leak upstream of the O2
sensor.
