My 2000 Lincoln town car is jerking and my check traction light is coming on my car will stall out but i can start it back up

If you have a switch for the traction control, the stalling of the engine can be reduced or eliminated by turning off the traction control.

The traction control probably has debris inside the rear emergency brakes. The traction control works by counting the speed of each wheel. When the part that counts the speed is blocked with debris, it thinks one wheel is slipping and kills the engine and applies the rear brake to the fastest spinning side.

The motor is suppose to lose rpm until the wheelspin is stopped. Then the motor is suppose to run normally. If the motor is completely dying you have a terrible problem with the sensor on the rear wheels.

The Traction control needs to be looked at, some Brake shops may be able to fix it. A dealer would have the tools. There should be nothing wrong with the engine, its suppose to react to the sensors.
