What are the symptoms of a sticky gas pedal, could someone please explain. I read all the posts but still don't fully understand the problem ? Thanks

I think a good word that was used in one of the posts to describe the problem is "notchy" - the pedal just feels "notchy" such that when you depress it, it does not feel like a smooth and continuopus motion, but rather "Sticks" a little at certain spots

There's an actual word for this -- it's called "stiction". It refers to the fact that the static coefficient of friction is greater than the dynamic coefficient of friction. In other words, if two objects are touching, it takes more force to initiate sliding movement between them, and then less force to keep the movement going.

The effect is always there. But normally, you shouldn't notice this in your throttle because the force necessary to overcome the static friction is much less than the preload force in the pedal return spring. In our case, however, it's greater than the spring preload, so you can feel it.
