"...I have been chasing a P1275 CEL code that I started getting when I put on 100-cell cats and had the car chipped. I also replaced all 4 oxygen sensors at that time. We have been playing with moving sensors and we even replaced one of the cats that the code reader said was running at a low efficiency. Like clockwork at 120-125 miles after we mess with the system I get the P1275 CEL again...

That made us think it was the cat on that side, which we replaced last week, I just put on 125 miles, and again got the P1275 CEL,..."

Hi Ed,
Just wondering about your code. Any new updates??? Let us know what you've come up with.

Thanks.

BTW, I see that you have posted an update. I just added it here: Help with P1275 Error Code.
