Question
I HAVE AN 2001 NISSAN ALTIMA THAT KEEPS STALLING AT LOW SPEEDS OR AT STOPS IT WILL JUST CUTOFF IT CRANKS BUT UP BUT IT WILL CONSTANTLY KEEP STALLING COULD I NEEDS A CRANKSHAFT POSITION SENSOR

Answer
Hi Bridgett -

If your check engine light is not on, then most likely all your sensors are functioning properly.

When was the last time you had a tune up? Could be as simple as spark plugs, ignition wires or carbon tracking in the distributor cap.

If that fails, also check the fuel pump. Could be that it is not feeding properly when car is idling or at low RPM's.

Hope this helps -
