When I let off the gas, the car jerks like I am pressing the brake real quick and then letting off but I am not. This car has 223K miles and still runs good except for this problem. I would love to be able to fix this car instead of buying a new one !! Thanks.

Check the torque motor mount located on the timing belt side of the engine (loos like a dog bone). It might be cracked. If its is cracked, it might be a good idea to replace it together with the front montor mount (close to the radiator).
