1993 Ford Taurus Problems
RepairPal has identified the most common problems with the 1993 Ford Taurus based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The engine may misfire and/or buck while driving at freeway speeds with no fault code stored in the powertrain control module (PCM). This can be caused by an intermittent fault with the camshaft synchronizer assembly. This condition can be diagnosed by monitoring knock sensor data as per Ford service bulletin #05-22-12. Replacement of the synchronizer assembly will be required to correct this concern.
Worn motor mounts can cause the motor to rise during acceleration, causing a clunking noise and possibly damaging the AC hoses. Damage to the AC hoses can cause a loss refrigerant resulting in no cold air from the AC. The motor mount will need to be replaced prior to repairing the damaged hose or the problem will continue.
While steering, if you hear a clunk or a rattle, or if you experience premature tire wear, this could indicate the inner tie rod ends are loose or worn and will require replacement.
Bad motor mounts can cause the motor to move excessively, which pulls on the MAP sensor vacumn hose every time you step on the gas pedal. This either weakens the hose so it collapses (causing low vacuum flow) or pulls the vacuum hose that connects the intake manifold to the MAP sensor completely off of the sensor. When the hose is disconnected from the MAP sensor, a full rich condition will result.
