Throttle lag / limp mode

NissanZ34

I have experienced throttle hesitation around 2300 rpm. I do not have a PCV delete kit so the oil goes back into the intake tubes just like OEM. After a while, the oil coats the Mass air flow sensors and provoke that bogging. I get the MAF sensors cleaned with brake cleaner and it goes away.

The only real fix is to get a PCV delete kit that consists of small air filters that collect the oil. A better alternative is to get an oil catch can kit, so the oil and debris are collected and can be emptied as well, whereas the filters from the PCV delete kit get clogged and need more extensive cleaning.
