Post FI HFCs Install/ SES or CEL Help!!

And that padding might just be sticking out of the heat shield... I sort of thought it could be wrapped around the threads of the sensor when it was installed but you won't really know till you go and try to remove it.

Were you able to check out the wiring harness for any damage?

That's what I said. I think best case would be to unplug and clean up that padding and then reseat the afr sensor and see if it clears the code. I don't see how any of that should even be there unless it was done upon original assembly of the header.

Not yet brother, its really cold out, and I didnt want to remove the air tubes, and leave the car without the air tubes connected, waiting on the new o2 sensor to come in the mail.

I don't think that padding could cause the CEL unless it was actually in the hole that the 02 threads into. But since you said nobody has removed it then I'm sure its just sticking out of the heat shield, take a look at my manifold. I pulled some of the padding threw like on yours.
