Why is my car stalling?

Question

Gas cap light on and codes p0102 & p0440. Gas cap replaced and MAF cleaned, and although the engine runs smooth when it is running, it stalls while driving and can be hard to restart. Any ideas?

Answer 1

You may have to replaced the MAF sensor, sometimes cleaning the sensor is not enough.

Thank you very much.  Your answer was spot on.  I had the MAF sensor tested and sure enough it was not responding.  Replaced the unit and the car is running fine.  Thanks again for your help.
