How long since it's been tuned with plugs, wires, cap, rotor, fuel filter? I would guess the fuel filter or a plugged catalytic converter. I hope this helps. Take care.

Sputtering has its roots in poor spark or fuel delivery. Could be failing spark plugs, coils, wires, or electrical supply to these. Could be dirty fuel injectors, faulty fuel pump & clogged fuel filter, dirty MAF, faulty Oxygen sensor, or even a vacuum leak. Backfires can be caused by these, as well, but could also be an ignition timing issue. One of the results of these is a clogged catalytic converter that just makes the problems worse. Correction is fairly simple: Have codes read to point you to where the problems might be. Then do a rigorous tune-up, and see if the converters need to be replaced.
