Found out it was an O2 sensor was not putting out any signal. While the sensor was bad, the car ran fine. No hesitation, and great pick-up. After the sensor was replaced, it passed emissions, but I could not tell any difference in performance. Still no hesitation, and great pick-up. But, I also picked-up 2 mpg. The O2 sensor is required if you want to keep from running rich or lean.
