If this is what I think it is, on the 3.5 Lit V6, you have an APS (Accelerator Position Sensor) and a TPS (Throttle Position Sensor). The accelerator pedal cable is NOT directly connected to the throttle body plate, it's connected to the APS. The APS sends its signal to the ETSCM (Electronic Throttle System Control Module) which in turn activates the ETS Motor located on the throttle body which opens/closes the throttle plate/butterfly. It's a very sofisticated electronic system. Both the APS and the TPS are known to go bad and simply replacing them is no guarantee of fixing problems in this system (often times it does, and frequently it doesn't). You should first verify there is a problem with these sensors (APS and or TPS). They are basic potentiometers (two circuits in each) which provide data to the computer regarding throttle opening for LOAD calculations (ignition timing, fuel injector pulse width, cruise control operation, etc). Best you have this system diagnosed by a professional technician who knows the system.

there is no adjustment on these tps's it's a drive by wire system. If you don't know the vehicle, dont post!
there's 2 sensors contained in the pedal sensor, and one on the throttle plate shaft, more often than not, it's the pedal sensor, and if you replaced that, it's the other one or a loose connection. did you reset the computer after replacing the pedal?
