Hi
Air flow sensor could be a problem.
Every time EML comes on the car computer will put the system into limp mode. To avoid any further damage to the engine.

once switch off, isolated and re-start will re-run the program and clear it temporary.
Ideally you need to get the car plugged in to a Diagnostic computer and see what fault code are stored.

Thanks

SOURCE: randomly loses power and sometime dies

1st thing to do is have the system tested for the code that caused the check engine light to come, you may also have a fuel pump starting to fail or many other things, the check engine light may be the key. How many wiles on the car?

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.

Under 2000 rpms runs bad/hesitates/check engine light


This IAC valve runs only when your foot is off the gas pedal. Mainly to keep the engine from stalling and keeping it at a safe RPM. If it is running bad under 2000RPM, more than likely its the IAC valve or a vacuum leak. Clean or replace the IAC valve....Hopefully this helps!!

My 2002 BMW318 TI has a warning light on the dash called EML - what does this mean?


Hello There

The EML stands for Engine Management Light . eml only comes on in BMW's when there is a serious problem with the engine. I'd suggest going to mecanic and have them read the code which will tell you what the problem is.

Hope This helps
