1995 Nissan Maxima Question: cutting off problem

Could be a multitude of things, so hard to guess without being able to drive the car or experience the problem first hand. It could be a vacuum leak, or idle speed control problem. Have seen air flow meters to cause a loss of power and stalling as well but all the problems I mention cause a Service Engine Soon light to illuminate. Scan tool information then shows lean mixture codes and Long and Short Term Fuel Trim figures to be radically off.

Knock sensor in itself shouldn't cause the car to cut out (a lot of Nissans store what seems like an erroneous knock sensor code).
I have seen a lot of air flow meters cause stalling but they flag a coded for lean conditions.

I had a similar problem with my 1995 Maxima. I took it to a local shop in Glendale, CA. They identified the knock sensor as the problem. They replaced it for me and the problem disappeared.
