Will the failure of the O2 sensors leave you stranded? Or does it start out with an SES light?
I guess it is OK to hijack my own thread.

Change the front two. They are the most important ones. I just did and they are very easy with the proper tool. The wiring connector is under the plastic head cover. Once you replace those front two, you will be pleasantly surprised at the extra power your car puts out. It made a real difference. Also think about the spark plugs if they are old. As for parts, look online, the O2 sensors can be had for about $65 each.
