Blowing through O2's like candy...
Hey I am wonder what all I need to look for if I am going through oxygen sensors every couple hundred miles. The story is I have a 95 with a 5.0 and an automatic with about 86,xxx on it I had a bad oil pan gasket leak that is now fixed that was leaking oil onto the sensor and the connection I have since fixed that and now installed my third 02 sensor. The truck ran great with the first two new ones then all of a sudden they went bad both had a little oil on them at the time. Do you think the oil would cause this? or could it be a clogged cat?
