I have a 1996 Nissan Altima GXE with 2.4 L engine, 5-speed transmission and 160K miles. I can feel that the car is hesitating slightly during acceleration, especially when it goes uphill.

It has a new distributor, spark plugs, spark wires replaced.

Anyone has some idea of what's wrong?

Thank you.

have u replaced all filters, air and gas.if your car can do a diagnostic test, do so...mite be a simple sensor.if all that fails, mite wanna get a check on cleaning fuel ejectors.. they mite be clogged. let me no results

Clean the throttle body most likely gummed up from age
