Cel p1276

Installed new precat O2 sensors and after 150 miles cel came on.

P1276 I did a bit of research and its a precat o2 aging/delay issue. Has anyone dealt with this cel given similar condition?

I used bosche 15182

986 606 127 01 (Porsche)

I also have headers if that matters and i'm using defoulers for the post o2's. so far no cel for those.

If you bought them on eBay or Amazon the sensors may be fake Bosch and junk.
