sorry!, the DTC for 133 means the oxy sensor is slow. B1S1 slow. It's slow for a reason. and not for too old.
remember that the 02 sensor swings. and if slow , there are problems.
yours is new, so why is it slow?
heater inside dead? (nah, there is a DTC for that)
air leaks.? near it? is my 1st guess, if wrong, it a fueling issue.. (dribbling injector ?)
TOOLS(free)
use a rubber hose held to ear. to find exh. leaks, (and rag trick is brilliant!!!)
i make a hose and duct tape (1million uses now, lol) to a 2 foot stick end (pipe or metal rod) and hold the rod in one hand and tube to an ear,
and can find leaks and not get burned on the 2000f exhaust.
on the 1996 and 1997, i have seen the 420s monitors suspended for ever. due to 133 or any other front sensor errors. its smart this way. (makes you find root cause it does)
the slow 133 might mean , its going in to closed loop then bouncing out, oddly.??
I'd put on after market headers if not living in CALIF. or states that run CALIF smog rules. NY is one that does i think?????? IIRC?
In calif. they do a visual ,and hark, omg a header, is this header on the EO list? they say and look, engineering order list.
that means the calif certified aftermarket list,
but here is some nice headers. that would not leak ever.
i like them all but the Thorely has a poor EGR port, (can change at drop of hat , any time in future)
i think Calmini wins the toss... in most cases.
but in every case , welding fitting can be required.

the donut gasket must not leak.
