Chuck the 02s are one of the most important parts for your car. DO NOT BUY AFTER MARKET get genuine FORD 02 sensors. If I remember right that is the same problem I had a few years ago. They can be tested, get the code book from autozone it tell you how. If you can afford them replace them. And don't give up we will get you through this.
