Those codes are for both of the O2 sensor. It could be a lot f things. I would first start by checking to a vacuum leak. Also if there is any other "P" codes I would try and fix them first. A few other things it might be it bad fuel pump, fuel injectrs, timing, PCV system, wiring. I hope this helps alittle. If you have any other question you can email me at sc377tt@Yahoo.com
Im not positive on this but my 99 contour just gave me the same code and it seems like either my battery or alternater needs to change going to try both tomorrow if it works ill let you know that was code number p1132
