This car has always suffered from poor throttle response. When cruising or entering the highway I have to step on the gas almost through the floor board for this car to move. Additional pressure on the gas pedal has 0 response unless I stick it to the stops.
I have sent it back to the dealership many times and they have "reprogrammed the transmission".
It does seem to come back with better response but this could be in my mind (sorta like the car runs better after it is washed).
Is there something else that needs to be checked?

Thanks
