I have a 99 Ford Taurus (DOHC) with 190,000 miles. About a week ago the engine light came on. I had it read and it showed one of the two 02 sensor behind the convertor was the problem. I decided to wait it out to see if it was just a "fluke". The car ran fine for about a week after that then it started idling rough. However, it's not giving me any codes. Runs fine while driving but when I come to a stop it idles rough and accasionally acts like it wants to die.
