Take out the air cleaner resonator. Disconnect the harness connectors for both the idle air control and the throttle position sensor. Label and then remove all the vacuum hoses from the throttle body.
Remove the bracket and the cables for the accelerator control from the throttle body. Loosen and remove the throttle body fasteners.
Lift the throttle body off the manifold. Remove the throttle body gasket and inspect it carefully. Replace the gasket as needed or re-install the old gasket to the throttle body after cleaning all the mating surfaces thoroughly.
Set the throttle body on the manifold and finger-tighten the fasteners. Torque the bolts to 89 inch pounds.
Install the cables and bracket for the accelerator cable, then reconnect the vacuum hoses. Reconnect the harness connectors for the throttle position sensor and the and idle air control valve, then replace the air cleaner resonator.
Depress the accelerator pedal to test its movement and to assure that there is no binding. Press the pedal to the floor one time then release it. Make the necessary adjustments.

1) If the gas pedal is hard to compress you could have a broken spring inside the throttle housing. The throttle housing is located in the sealed compartment of the cruise control housing.(The housing with the rubber bladder.) You will have to remove the rubber covering to inspect the inner workings of the throttle mechanism. If every thing looks intact push on the accelerator. If it is still hard to push in, you could have a rusty cable.
2) A simple can of WD-40 should be applied lightly to the inner workings of the housing parts.
Try the throttle again and if it is still hard to push, check the connections of the cables to the throttle apparatus. Use the long plastic tube on the spray nozzle of your WD-40 can to shoot lubricant in to the small openings of the cable sleeve.
3) It may take a few minutes of manipulating the throttle to loosen up the corroded cable connections. Once the cable slides and the throttle seems to move freely take a dab of Vaseline and coat the ends of the cable connections. Vaseline will keep the moving parts lubricated and protect the connections from becoming more corroded.
4) By lubricating all moving linkages, you can prevent further throttle sticking. Make sure you replace all coverings back to the way they were when you started. Sit in the drivers seat and push the throttle pedal a few times to ensure that the throttle is no longer sticking.
5) Take your car out for a short spin in a unpopulated area such as a empty parking lot. Start and stop the vehicle numerous times to check it out. If the gas sticks at a slow operating speed, you can simply put the car in to neutral, apply the brakes and switch the ignition off. It is always better to be safe ..
However for an easy solution check cable to throttle body, it may be kinked. This is a common problem. Remove the throttle body and clean the throttle plate with a throttle body cleaner. Clean the front and back of the plate. Just spray and wipe off with a rag. Do not scrub with a wire brush. Doing this can damage the throttle plate. You can buy throttle body cleaner at most parts stores. Make sure you clean up your IAC valve while its off, that thing gets gunked up bad after a while.

Throttle position (TP) sensor C/accelerator pedal
position (APP) sensor ? - range/performance problem
Possible Causes: Accelerator cable adjustment, TP/APP sensor
Throttle position (TP) switch C/accelerator pedal position
(APP) switch ? - range/performance problem
Accelerator cable adjustment, TP/APP switch
This might only be an adjustment issue--make sure the throttle cable isn't so tight that the throttle cannot fully close.
If the cable is OK, it is probably the accelerator position sensor under the pedal.
There are procedures for testing the unit that I will paste below if you care to try them.
If you just want a shop to fix it, the part is about $50 and labor should only be 30 minutes.
Operation The sensor is made up of the two individual sensors within a single housing. Each sensor has a unique functionality to determine pedal position. The APP system along with the Powertrain Control Module (PCM) is used to calculate and control the amount of acceleration and deceleration through fuel injector control.
