1997 Dodge Ram 1500 Oxygen Sensor

  1. I am attempting to replace my pre-cat oxygen sensor on my 1997 Ram, however,
    I cannot seem to get to it. Has anyone found an easier way to get to the
    sensor. Also, for a while my check engine light was reporting too rich/too
    lean for my post-cat sensor, and I never replaced it. Eventually, the light
    went off, and stayed off. Recently, my engine began to hesitate when I
    accelerated, and the check engine light came back on. This time the check
    engine light read that the pre-cat sensor was responding too slow. Could
    this be related to my engine problems, aka the sensor failing and reacting,
    thus altering my injecting stream?
