I have just came into a 96 Maxima which tends to stall at red lights and lurches. I got the trouble codes from the computer and it listed a bunch of the sensors(o2, cam, knock). I replaced all the ones listed but that didn't seem to solve the problem. Any ideas?

maf sensor is bad?

My 95 used to do something similar a few years ago. it would idle really weak, sputter, and stall, especially in the winter. The dealer replaced my IAC valve under warranty and that seemed to do the trick. no problems since. but i had to take it to a couple dealers before the problem was found.

Remember that the ECU is just a dumb computer. It is only telling you that it is not getting the correct signal from some sensors. It is not testing the sensor, it just not getting the output from the sensor that it's programmed to see.

You also can't tell if the sensor error is causing the problem or if the error is a by-product of something else. A few years ago (on a different car) I got a bad o2 sensor code. The root cause was a stuck open thermostat!

If you get error codes for a lot of different sensors all at once it sounds like you've got a more general electrical or mechanical problem.

It could be something as simple as a bad ground or corroded battery terminals. Since the engine power circuits originate at the positive terminal using male/female connectors, I would clean those first. You could also have a wiring harness problem like a loose or corroded connector at the ECU.
