I have a 93 chrysler lebaron v6 4 door 3.2 liter. While accelerating and driving at constant speed below 2500 rpm. the engine seems to hesitate as if the fuel pressure dropped. the hesitation is not that severe, however I want to find out what is going wrong before it does become severe. One other thing that I have noticed lately is that the car has been getting harder to start. The fuel pump was just replaced about 2 1/2 years ago. Could that be the problem again. Thank you
