95 nissan maxima 3.0. have replaced knock sensor both 02 sensors, computer,and mass airflow sensor 3 times. the mass airflow sensor makes the car run right but it doesn't last it goes bad fast its been to the dealor 3 times and 2 other mechanics and has cost alot of money, i just replaced the mass air flow again it idles between 800 and 1100 rpms in park and 700 in drive. and sometimes it sounds like it has a high performance exhaust under the hood between 2000 and 2500 rpms while driving please help.
I would have the charging system checked for over-voltage and AC ripple. There maybe a hidden wire harness problem if the charging system is okay. Wiggle test the wire harness while the engine is running to help locate the problem area. That is way to many parts replaced.

my 2000 nissan maxima is hesitating sometimes and sometimes dying. When idling down to low RPMs., it cuts off. Or, sometimes it doesnt want to idle at all and it dies. But, it doesnt do this all the time. Checked mass airflow censor but still not sure. is a 2002 mass airflow sensor compatible with a 2000 modile? Or could it be something like a vacuum leak, 02 sensor or something else?
