Update,

Got codes listed in previous post - and I replaced just the Oxygen Sensor and since then no more CEL. It has been two weeks since installing the new O2 .

Did need an O2 socket from Harbour Freight that cost five-dollars in order to unscrew the old sensor, easy.

The electrical connection end of the O2 sensor and the routing of the wire was the hardest part, but not bad.

Have noticed that with the new O2 sensor my car seems to start-up quicker.
