2001 Chevy Malibu w/ ~81,000 miles. When I press the gas conservatively, the car accelerates fine up to about 15-20 mph then it starts getting sluggish and sort of jumpy. By " jumpy" I mean that it feels like its either not getting gas or not burning the gas that its getting. I don't want to say that its misfiring because I don't know for sure if it is. The fastest I go to and from work is 40 mph and its tough to get up to that speed. This problem is more noticeable/severe when pressing the gas liberally or when attempting to accelerate or keep a constant speed going up a hill. I just had the intake manifold gasket replaced and the fuel filter replaced. Every garage that I call or stop at says it could be any number of things from plugs and/or wires to fuel pump, to catalytic converter, and so on.
