Replace the accelerator cable since it is worn and sticking. It will loosen up as you say altough someday it will jamb up while your driving it which will be a dissater in most cases

The gas pedal is recalled on many fords and toyotas and is a well known problem, get the pedal replaced

sounds like your brakes are taking too long to disengage. Your problem may not be your gas pedal. If your brakes are sticking it could be holding your acceleration back just a bit until the car gets moving again.

Try cleaning the throttle body. Use a throttle body cleaner and do not flood the throttle body with the cleaner. You will have to open the throttle up and spray around the butterfly. It most likely carbon buildup and causing the butterfly to stick when you accelerate. A couple of short sprays will be fine, clean with a cloth. You will see a lot of black buildup flow out of the throttle body. After you wipe dry, let the intake hose stay off for a few minutes for the throttle to dry out.

You may be able to fix this by adjusting the clutch pedal height. There is an adjustment rod at the top of the clutch pedal under the dash. Loosen the jam nut and turn the push rod to lengthen it. Retighten the jam nut and test drive the vehicle.

'As in neutral' ? so the eingine accelerates but the car does not move? Or do you mean nothing happens? I had a problem where pushing on the accelerator and the car did not move and the engine stayed in idle. At first I thought it was the throttle cabel but the dealer could not find the problem, and of course, when I took it to the dealer the problem would not occur but as soon as I drove it off the lot it refused to accelerate across an intersection, no matter how hard I pushed on the accelerator. I solved the problem by pulling the air horn from the carb intake (fuel injection, this would be the air horn covering the throttle butterfly) with the rubber pulled from the air horn I saw a small blue screw with a sticker waring not to turn more than a quater turn at t time. I turned it one quarter turn (guessing, left or right, 50/50 chance) and the problem was solved. Apparently this is an adjustment that touches the leading edge of the butterfly keeping it from closing completely against the air intake horn and STICKING. Carbon build up will cause the buterfly flapper to stick tight and the electronic controled throttle will not break it loose no matter how hard you stomp on the accelerator. This car was not a SantaFe but you problem sounds similar. Hope this helps someone.

your throttle body flap is sticking, just remove air intake hose hold throttle open and clean inside with carb cleaner and toothbrush, this should fix, if not throttle body will have to be replaced. and its pricey

Take off the throttle body (very easy to do) and use carb cleaner to clean off the gunk. You have to clean both sides of the butterfly.
