Hello,

I've been doing a lot of driving the back roads and looking in the woods for some trees. Rather than start and stop and run the battery down and risk not having enough to start the car again I mostly leave the car running on the side of the gravel road while I poke into the woods for a few minutes and look around. When I get back to the car it will trigger a oxygen sensor code and the check engin light stays on. If I reset, the light will trip back on within half a day or two. Only ever at idle.

Not enough to make me want to buy a new oxygen sensor for 100 + $

But can anybody recommend a quick fix that has squeezed a bit more life out of their sensor or connections ?

I had the sensor out of the muffler pipe last winter when I needed to weld the downpipe at the Y. Threads looked good and so did all the connections. It started doing this a couple months ago.

Any tests or checks I could do to trouble shoot this problem?
