2002 Nissan Sentra Chugging when you give it gas.

Ignition wire

tune-up, dirty gas, dirty air filter...when last completed?

There could be a laundry list of things wrong. Do you have good throttle response? Does it Idle without dieing? Check your fuel pressure with specs. If not up to par. Then yes you are right. Otherwise Could be fuel filter, broken or cracked vacuum line, MAP sensor, TPS sensor, IAC motor just to name a few things. need to hook up to scanner and check parimaters.

the fuel pump is going bad

Sounds like ignition components may need replaced like the coils and wires.

the first thing i would do is put some STP gas treatment with fuel injector cleaner in it also make sure you have at less a half tank of gas in it and drive it on a back road where you can get up to 55mph Merry Christmas and Happy New Year as always wish you the best of luck Michigan Man

it could be fuel pump problem plug leads ,coil pack

check oil level might be too full or air cleaner box not fitted correctly or hose from air cleaner to engine not sealed correctly.

Could also be a faulty mass air flow meter, or throttle position sensor. It's hard to tell, you need to take it to a shop to be properly diagnosed.

is this a 1.8 liter?? check engine light on?? if so, what is the coed??
