Question about 2000 Nissan Xterra
When the car is at idle, there is a small intermittent shudder but no rpm loss. When the engine is put under even a small load, like climbing a hill or accelerating from stop, it has significant loss of power, like it is being starved for fuel. any ideas?
I was factory trained to work on these cars, the problems i found for this symptom where this, a cracked air intake rubber flex hose, crack is on bottom and opens up when u accelerate, next is a defective MAF, which is a Mass Airflow sensor, neither of these two problems will set a code.

It's quite possible to ruin a fuel pump by letting it run dry, especially if it already has years of use. When you first turn on the key, leave the door open and see if you can hear a high pitched whine for about three seconds. That would be the pump priming the system. If you don't hear it, then the pump isn't working. Be sure to turn the key of for about 10 seconds before you try listenng again(it has to reset). It can be hard to hear, especially over the key buzzer.

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.
