Hi Mike,
When I had the 60K checkup on my 5000S, dealer replaced the O2 sensor so
yours might be on its way out. My friend (shadetree mechanic
extraordinaire) told me since O2 sensor sits on exhaust manifold side, it
gets lots o' heat and sometimes can be VERY stubborn to remove. I took this
as a hint not to make him try or try it myself. So I had dealer do it. I
may just be a wimp.
I think the mail order places need to know how many wires come out of the
O2 sensor. Think there are 2 wire and 3 wire sensors. Of course 3 wire ones
cost more. Linda at Carlsen might give you a good deal.
That's all I know.
