Hello My name is Caswallon from St. vincent and the Grenadines I have a Nissan Wingroad WYF11 2002 That shuts down. I have changed the Airflow, coolant temperature, and the crank shaft sensors and the gas, oil and air filters, but it still happens. What can I do to solve this problem?

1st, Nissan had a recall on Crank position sensors for 2002-2006 Altima's. Check with you dealer before you go doing any repairs. You may discover you can get your car repaired at no charge.
NHTSA Campaign ID number :O7V527000
Symptom: Erratic behavior. Stalling and no starts and very difficult to diagnose due to the time frame in which the component actually malfunctions. The warranty should not be limited to the original owner.
I would also need more specifics as to which engine you have so I might assist you in where the location of the sensor is. The Altima had a 4 and a 6 cyl engine offered that year.

IT IS ON THE HOSE THAT BRINGS AIR INTO THE AIR FILTER HOUSING

SOURCE: black smoke on my nissan terrano when you put

black smoke usually indicates to much fuel being delivered. If this is the case you need to correct it soon or you will damage the catalytic convertor. What year is the vehicle and how many miles on it? Is there a check engine light on? this info would help
