Traction control light comes on and can't accelerate as usual and I am not spinning wheels, problem goes away if I turn off engine and restart the engine. Usually happens when I tow my trailer or boat, hardly ever when not towing.

Re: tractio control light comes on and can't
You most likely have a problem with one of the ABS wheel speed sensors or the ABS unit itself. ABS and Traction Control work together in your vehicle. The system thinks that one of the wheels isn't turning and then limits the power or may even apply the brakes on the other wheels in an attempt to remedy the problem. You'll most likely need to have the system hooked up to so the sensor inputs can be checked for faults.

The traction control system DOES cut your engine power when the tires spin. That is by design. The system cuts engine power to stop the wheels spinning and restores power once the wheels regain traction. It feels odd when the tires spin and power cuts out. It's good practice to lift off the accelerator when the system kicks in. Otherwise, if you are on gravel or slick streets the tires may spin, stop when traction control kicks in, and then spin again when power is restored. It is not an "elegant" solution but it does work for the most part.
Hello! From what you are saying, am I correct to assume that when you turn off TC the light goes off? if this is the case and no trouble lights or messages are showing I suspect the Vehicle Speed Sensor (VSS) is faulty...VSS information is used to calculate torque convertor application, fuel cut off/speed and governance strategies... Modified drive train components such as final gear sets and/or tires alter VSS input values to the PCM...Have you changed tire /wheel size? If not it looks like a defective VSS...See diagram below...A couple of questions; Lets say your doing 60 MPH and want to pass...If you stomp on it does it perform in a normal fashion? Are there any other symptoms? If all is well then change the VSS...If it always has trouble accelerating the Throttle Positioning Sensor (TPS) may be at fault...It can be tested with a voltmeter...The VSS can not...Send a comment....Guru...Saailer
TRACTION CONTROL: An enhancement of an existing ABS system that prevents wheel spin while accelerating on wet or slick surfaces. It uses the same wheel speed sensors to monitor wheel speed during acceleration, but requires some additional control solenoids and a pump to apply braking pressure to control wheel spin. The traction control system brakes the drive wheel that's starting to spin to shift torque to the opposite drive wheel that still has traction. Most traction control systems only operate at speeds up to about 30 mph. Additional control strategies that some traction control systems use to limit wheel spin include reducing the throttle opening, upshifting the transmission, retarding spark timing and deactivating fuel injectors.
you can check weather the traction control is working by putting the car in first gear and with one wheel on grass and the other on tarmac pull away as fast as you can.you should feel the power drop and when both wheels match each other for rotation a clean acceleration will occur.i.e.the car will not pull toward the tarmac...and spin on the grass.as this is part of the abs system it could be your brakes are due for renewal.they have wear indicators...take a wheel off and look through the caliper end, over 1/8th inch is just about the lowest to go.
Hello Jeremy. When your traction light comes on it is indicating wheel spin on acceleration. To prevent wheel spin an onboard computer reduces engine power to limit the wheel spin. Some, if not most, cars equipped with this feature will also apply the brakes if wheel spin continues after reducing engine power. Hope this answers your question. Thank you for using Fixya!
Traction control helps limit tire slip in acceleration on slippery surfaces. In the past you had to feather the gas pedal to prevent the drive wheels from spinning wildly on slippery pavement. Many of today's vehicles employ electronic controls to limit power delivery for the driver, eliminating wheel slip and helping the driver accelerate under control. Don't turn it off.
that is what it is desgined to do - reduce acceleration and apply the brakes intermittently when the wheels spin. You have a switch you cn push to disable it. You need to disable each time you start car. See owner manual.

1996 Contour, Mystique Workshop Manual
DESCRIPTION AND OPERATION
Traction Control System
The optional traction control system is designed to control wheel spin when accelerating on slippery or loose surfaces. Traction control system is available only with anti-lock brakes.
The traction control system includes the following components:
Hydraulic control unit.
Throttle control actuator (9N825).
Traction control switch.
Traction control warning indicator.
Front brake anti-lock sensor (2C204).
Rear brake anti-lock sensor (2C190).
The traction control system operates as follows:
System functions by transferring torque from the spinning wheel to the wheel with the most traction.
This is achieved by applying the brake at the spinning wheel through the hydraulic control unit or reducing the throttle opening.
Traction control braking and throttle control occur at vehicle speeds up to 50 km/h (30 mph).
At vehicle speeds above 50 km/h (30 mph), only throttle limiting control is used.
If speed control is operating when traction control system engages the traction control system will disengage speed control through the use of a speed control relay. This action is the same as applying the brake pedal with speed control engaged.
Traction Control Switch
The traction control switch is located on the instrument panel, left of the steering column.
