Engine Performance problem
1996 Nissan Maxima 6 cyl Two Wheel Drive Automatic 195000 miles
About a year ago, my car started idling rough. It would shudder when I was idling. After a few months it started idling so rough that it would die. The only way to keep it from dying was to give it gas while stopped. It didn't shudder if I put the car in neutral or park. The problem only existed when in park, reverse, etc. After researching, I replaced the mass air flow sensor. This fixed the problem. After about 6 months the same problem started again. It continued to get worse until it started dying again. I bought another mass air flow sensor, installed it, and it didn't seem to help. I took it back and swapped it for another one, just in case the first one was bad as I was purchasing remanufactured mass air flow sensor and not new. So, after putting the second sensor on since the problem came back, I'm not sure that the sensor is the problem this time. What else could it be? The symptoms are no different than when I changed the sensor and it fixed it temporarily.
