I have a 2002 mustang gt with 65,000 miles on it. At times it is very hard to start. I have pulled the mass air flow sensor off and cleaned it. No warning lights have came on. I don't think the fuel filter has ever been changed so i plan on changing that anyway. But i notice when i hit the gas a sqeuk type noise comes from under the hood when i am hitting the gas especially pulling away at a stop sign when the engine is under a load. Does anyonehave any suggestions on what i can do about my car not wanting to start at times. It doesn't do it all the times just sometimes. Thanks in advance.

 

anyone have any ideas for me to try?
