Code 44

[Jetjock]

No sooner than I fix the Code 43 than I get another code. This time a Code 44. I pulled it up and it's the left O2 sensor. I had this before on another car and it was relatively simple to fix by running the engine up and it cleared the code. I plan to jack it up and take a look to see if there are any wiring problems under there. I did move the wires around to put in the knock sensor and I might have done something at that time but the service engine soon light didn't come on for a long time while driving it. The car does have over 100,000 miles on it so it's not surprising that stuff starts to fail but it never came on before. Any thoughts?

100K miles on an O2 sensor it?s probably just time to replace it. They tend to foul around that time.

Not a bad idea to change O2s with plug change.

As far as I can tell, GM discontinued the O2 sensor for the LT5. What are everyone using to replace sensor? What is the length of the cable?

I recently picked up a couple of AC Delco off ebay. RA has sensors just not Delco. But I would not use Bosch.

I've been having good results with NTK O2 sensors
