My pathfinder stalls while driving in stop and go traffic. Doesn't do it all the time but when idling. Easy to restart. Trying to find out of it's my maf sensor. Pulled codes and got one that said maf sensor or circuit failure, and additional code for knock sensor. Tested voltage on maf sensor connection and is good. Trying to find out if the two codes are related. Also, trying to find out if it's possibly my fuel pump. Sound the fuel pump usually makes when starting up vehicle can hardly be heard. Very little hissing sound from gas tank when you unscrew the gas cap.

My pathfinder does the same thing I have a 95 though. Anytime I go to take off from a stop it tries to stall if I put it in neutral and step on the gas a bit it wont do it but then doesn't really wanna go any where. && When it does stall iot doesn't want to start up for a while only turn over but no start for a couple of hours I can come back later && it would run fine sometimes. But a friend of mine said its either the mass air flow sensor or the egr valve and from what i've heard you can easily bypass the egr valve. But if ya find out let me know.
