Rpm won't go up even in idle or in gear

Nissan Altima 2002 automatic sedan 200000 miles
In idle car starts good but even if I press gas pedal all theway it won't go up more than 1500 and engine start shaking as well and in gear same thing can't drive more than 10 mile/hr. Scanner shows codes for throttle and i replaced that... again shows the same. Anybody can help to figure out the problem???

Cylinder missing. Code reader at auto parts store will tell which cylinder is missing. They go in order left to right 1234 looking at the emgine. Most likely it is an ignition coil. Take off cover unplug the bad coil. Loosen screw and pull it up off the plug and install the new coil. Takes 5 minutes in the auto parts store parking lot.
