SOURCE: 000 NISSAN Xterra -- after warming up, loses RPM by 500-1000..... have replaced ignition wires and distributor, checked mass air flow sensor and OK.....

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.

SOURCE: Very rough idle and low rpm and flashing service engine light.

Don't think it's major could be any number of sensors. Any autozone will run a free scan and point you in the right direction.

Idling is too slow at 500 rpm.......think about at least 650 rpm to charge the battery and keep up inertia for better take-off power.
Find out how to increase rpm,whether it's a screw-stop adjustment or a timing problem. don-ohio (:^)

At 4000 rpm the motor cuts out shuts down but it runs smooth from800 to 3900 rpm and it has a rough idle.


Kind of sounds like low fuel pressure or bad ignition. Clean spark plugs, distributer, and fuel filter.

This rough idle business; With the AC on at a stop, the idle is about 600 to 700 rpm and vibrates the cabin. Can the dealer change a computer setting to correct this?


Problem on focus too . Without A/C on it idle's smooth . With A/C on the PCM - engine computer should raise the idle rpm. 850 . The only way to raise the idle would be to have PCM flashed programmed with up dated software . Adjusting the idle anyother way would cause check engine light problem , Wouldn't be able to get it to go out. Your best bet ,take it to the ford dealer and have the PCM reflashed .
