When I am traveling at any speed and I suddenly and quickly remove my foot from the accerator, the car jerks some. What could be causing this? It seem to happen more when the car has warmed up. Is there a part that attaches to the gas peddle system that allow for a smooth "slowing down"? Please help!!!

 

Check to see if it's caught on some thign of get a new car LOL

 

you need to elaborate on RPM, speed, etc...

kinda hard to diagnose any kind of general problem like that w/o more specifics.

 

sounds normal to me.
