Intermittent P0130 code

[mrbieler]

97 Disco with 146000 miles. Original O2 sensors. Mpg has been a consistent 13 mpg for years in stop and go la traffic.

It's been throwing P0130 for a few months. Popped up in march, but truck showed no change in performance. Cleared it and it was gone for 8 weeks. Popped up again in early May. Now a third time.

Truck is a daily driver and I have seen no performance change.

I know it's time to pop in new sensors and that's in the schedule this month, but this intermittent code has me wondering what I could be missing.

Check for corrosion in the connector. Clean it really good. I've seen water or oil migrate up the whole wire to the ecu

Yeah. When I'm under it next week for some scheduled work, I'm going to pull the connectors and sensors to clean them and see what happens. Thanks.

Just realized my post count is only 10. LOL. I assume there was a purge a while ago. I was pretty prolific before my back blew up.
