2002 chevy impala hesitation?
looked at a 2002 impala today and while I was driving it hesitated on accelerating once or twice and while it was parked I left it running and it started putt putting a little like it was idleing and it died down a little for a few seconds and went back to its normal idleing sound now why is that .the guy said it might need a tune up and that the car was siting for a couple months . does the car sound like it needs something else im thinking fuel injectors or fuel pump but I aint a gear head so I aint really got the first clue or am I over thinking it lol and all it needs is a tune up

Fuel filters and bad fuel pumps can cause a fuel starvation problem. Replace the fuel filter, and have fuel pressure checked at fuel rail to ensure the proper psi. If there is a misfire, it will cause the car to hesitate, shake, and idle very rough pretty much all the time, and it will smooth out a bit when you reach a higher speed. Replace spark plugs and wires, sometimes a bad coil is to blame, and will need replacement.
