I own a 1997 Nissan truck xe and I am looking for the mass air flow sensor but cannot find it?

SOURCE: mass air flow sensor

maf sensors identify the amount of air flow flowing in the intake. the sensor works with the throttle so it knows how much air is coming in to add the proper amount of fuel to mix with the air. Easy to pull and replace.

I had a problem on my Nissan Xterra 2000. Symptons sound similar. In my case, it ran fine for a while and then suddenly the engine starts to stumble and lose output. At one point it did not even have enough HP to move. Irregular idling too. Thought it was water in my fuel. Bought water remover from the store and added to gas tank. Problem did not go away. Instead, "Service Engine Soon" light came on. Had to have it towed to the dealer as there was no way the engine could keep up with traffic. Dealer replaced the "Crank Position Sensor" today. Parts $33.00, Labor: $300 (about 3 hrs worth of work). Seems to work fine now but I will wait and see. Dealer also stated that Distributor bearing appears to be noisy and will need to be replaced sooner or later. I will wait for it to go before I fix that.

it soubds like you have a vacum leak problem listen for a "his" with the engine running. you may want to take apiece of hose @2-3ft long put one end at you ear and probe arround the top of the engine arrount the intake manafold and any hoses when you find the his find wher it goes and replace repair the hose. it may also be your pcvvalve thst is stuck it willcome out of the top of your valve cover and plug right the intake hose right before the throttle body
