I had this problem on my integra now this car is starting to show signs as well
Since i built it it was great until few weeks ago
When i try to keep the throttle steady driving around parking lot and i hit a bump my foot moves the throttle and sets off a chain reaction because the car jerks forward and so on

I either have to let go the gas or step on it.
It looks retarded and its blowing my drivetrain out because the car jerks pretty hard
I have hasport mounts and skunk2 coilovers so theres not much movement.pretty stiff ride
