Hi folks,

I read so many things about that engine, specially about the pre-cat issue that comes since the Altimas 02.

What really changed in that famous engine? Did they change the pre-cat position? So far I just know that they changed the sensor and did some "improvements".

Also the say that the pre-cat position is the same in all nissan engines, is not just in the QR25DE. Is that true?

From what I remember, there was a design change in late 03-early 04 to fix the issue on all QR cars.
