that kind of sounds like it could be my problem as I drove it more this morning....

Topped off radiator, and that seems to be stopping the overheating....imagine that <img src="/forums/images/graemlins/shiner.gif" alt="" />

It is stalling out every-so-often its very inconsistent, but usually happen once in a driving trip (appr 1-4 miles)

And, as you said, only was after the engine heated up, this morning after topping off I drove for probably 1.5-2 miles with no symptoms....

Where can I pick up the 02 sensor at and how hard is it to replace.....
