I just replaced my MAF sensor with the Maxima one and it is now running great. My 2001 Pathfinder SE was exhibiting all of the same symptoms described by Pmoore304 to include the transmission "flaring" problem that he described so well. I did first replace the fuel filter but that wasn't the smoking gun - the MAF was definitely the culprit. The truck was bogging down and loosing powder above 3K rpms, but before that problem got progressively worse to the point of nearly stranding me on I95, the transmission would "flare" and not go into the proper gear when accelerating. This could be alleviated by slowly letting off on the accelerator until the transmission felt like it found itself and went back into gear providing torque to the rear wheels. Who knew that a problem with a mass air flow sensor could cause such a major engine as well as transmission performance issue? I ordered the part (the Maxima one) from Courtesy Nissan shipped for about $90. I installed just the sensor into the existing air flow tube in about 15 min and problem solved. The truck now drives like brand new with outstanding acceleration and no transmission shifting issues. I just wanted to say "thank you very much" for all those that contributed to this thread (especially 88pathoffroad) and other similar ones on this site related to trouble shooting the MAF and providing an alternative MAF solution (the Maxima one) that saved me at least $400.
