Thanks a lot for the help.
Here is another question: Has anyone found it hard to start the car (excessive cranking) when the car is low on gas (and maybe on an incline such as a hill)?
I had problems starting my car when it was low on gas and i guess it has something to do with the fact that there was not enough fuel pressure because the fuel pump was sucking air. The air did start and drive after I cranked it with my foot on the gas pedal.
