Q: My car jerks/pulls when letting off the gas pedal
I recently bought a used 2007 Saturn Ion with 66k miles on it. The dealer that I bought it from said that it was pre inspected and all fluids were changed. I have noticed that the car will start to jerk/pull when I let off the gas pedal. It is only noticeable at speeds of 45 mph or higher. It doesn't happen when I accelerate or decelerate, only when I take my foot off the gas to coast. I don't hear any unusual noises, the car sounds fine. I did notice fluid on the ground after I had my car on and AC running for about 5 minutes, but figured it was from having the AC on. Thanks for your help.
My car has 66000 miles.
My car has an automatic transmission.

Hello. A few of the things that could produce the symptoms you are experiencing are adirty throttle body, or perhapsworn motor mounts.
Your vehicle uses an electronic throttle body, that is an engine throttle plate that is actuated electronically. Over time the throttle plate can build up varnish and grime from the fuel, which can interfere with the operation of the throttle plate. A stuck or binding throttle plate, either as a result of grime, or a faulty throttle body motor can produce the symptoms you are experiencing.
磨损的电动机安装座也可以产生类似的症状。磨损的安装座可能会导致车辆在发动机舱中来回移动，导致车辆混乱。
由于导致问题发生的非常具体的条件，我建议将车辆驱动和诊断为专业技术人员，以帮助determine the exact cause of the jerking/pulling issue.
