I HAVE A 1997 MERCURY SABLE IT HAS ABOUT 213000 MILES ON IT WHICH THE MOTOR STILL RUNS GOOD DOES NOT USE OIL OR SMOKE . BUT
IT KIND OF JERKS WHEN TAKING OFF WHEN I GIVE IT GAS AND IT ALSO VIBRATES. COULD THIS BE CAUSED FROM A BROKE MOTOR MOUNT. I WAS TOLD THAT I HAD A BROKEN MOTOR MOUNT ON THE LEFT FRONT. ALSO IF MY WATER PUMP WERE TO BE BAD WHAT WOULD THE CAR BE DOING OR COULD IT STILL BE OPERATIONAL.

could be motor mount, if your water pump was bad then she would run hot when your stop if you give it some gas the temp hand will start going down, or it will start squeling.

Suggested Repair

Inspect and replace the reported broken left front motor mount. A failing water pump would more likely cause overheating when stopped, a temperature drop under acceleration, or squealing rather than the takeoff jerk and vibration.

Conversation Summary

The owner of a 1997 Mercury Sable with about 213,000 miles reports jerking when accelerating from a stop and vibration. The engine otherwise runs well without oil use or smoke. A broken left front motor mount was previously reported, and the owner also asks how a bad water pump would behave. The expert says a motor mount could cause the symptoms, while a bad water pump would typically make the engine run hot when stopped, drop in temperature when given gas, or squeal.
