I have a 1995 Plymouth Acclaim. The mileage is 177,745 miles. I have noticed that sometimes when I put my foot on the gas pedal it doesn't want to go and then I will let up on the gas pedal and it will take right off. I keep it in our garage at night. Could there be moisture in the gas tank? I just had the starter and oxygen sensor replaced. I can't afford a lot. I have noticed there is moisture in the headlight cover.
My best guess would be a weak fuel pump that may need to be replaced but before buying a new fuel pump try to drain all the gas out of the tank & refill it with new gas.
Another problem that would have this same symptom does not have anything to do with the fuel intake system but has to do with haveing bad engine compression. Bad Engine compression can be caused by a blown head gasked or you may just have bad compression bolts. As for the moisture in the headlight houseing that is completly normale and that just comes with the age of a vehical.
