transmission or plugs problem ? on 1996 Nissan Maxima

My car is just hard to move forward ( still running but vibrated) even I strongly push the gas pedal after I stopped or turned. I hear the vibration ( it seems want to turn the engine off) by the steering wheel. If the transmission problem, how can I check it? If the ignition misfire, do I have to replace all 6 plugs? thanks
