Check Engine light goes on and off for the last 3 years

I have a 1999 Toyota Solara and for the last 3 years the (Check Engine
light) goes on and off.

Cars seems to be running OK. Went to Auto Zone when I catch it on and they
said it's a P1133.

Lately the lights on longer, half the time. The car still runs fine. Auto
Zone says 4 codes show up only two different ones P1133 and P1153

P1133 Heated Oxygen Sensor (HO2S) insufficient switching bank 1 sensor 1
(Rear Bank)

P1153 Heated Oxygen Sensor (HO2S) insufficient switching bank 2 sensor 1
(Front Bank)

Before I go to the dealer and pay the big bucks I'd like
your opinion.

Thanks in advance

It sounds like the O2 sensors are getting old. If you want to save some
money, purchase the O2 sensors at a Toyota dealer and change them yourself.
It is a simple operation.
