I have a 1997 Hyundai Sonata. The whole car and the engine vibrates
whenever I stop or/and on drive only. It uses about a gallon per 5 miles.
I checked every part of the engine and I know that it is not leaking any
gas. I suspect the throttle position sensor could cause some vibration
but what of the gas per mile problem?

I would get the ignition leads checked.
 
The engine check lamp is on. The code inititially pointed to the throttle
position sensor, however, the problem was not corrected even after I
replaced the sensor.
 
I believe the sensor on this car is adjustable. Did you notice whether
it's adjustable, and if so, are you sure it's adjusted properly? I
presume you cleared the codes and none returned.
