So the code relates to the O2 sensor detecting a lean condition (too much oxygen in the exhaust). This can be due to a number of vacuum pipe conditions, but most commonly is an air leak in an air hose, a loose air hose or PCV hose connection loose. Sometimes the PCV can stick open causing this condition too but this can be removed and cleaned. Using Fuel Injector cleaner may help if an injector is getting clogged up which can present this code also. And as you mention, it could be a hole in the exhaust manifold to the first O2 sensor. Enough to check out, but I'd look at the hose connections first.

Hey . Corolla Corolla Comressor 1.8, 165 kw, Year 2005 engine 2ZZ-GE.
In my car, fuel nozzles with spare part number 23250-YW201.
Is the nozzle original?
