I just realized that I said something that doesn't make sense and I am now far more confused. 1126 is lean, but negative fuel trim is the car pulling fuel out. I typed that earlier in a rush and didn't realize what I had said.

But that was the original reason I recommended changing the o2 sensors in the first place - things are pointing to a lean condition but the sensors are reading rich and hence the ecu is pulling fuel.

I'm not sure I'm helping at this point lol. This seems really screwy to me though and I'm not sure I can explain it any further at this point. Sorry dude

. I would still check for leaks if you've had every off recently but the continued 1126 when sensors are detecting rich and pulling fuel back has got me thoroughly confused.
