1991 Mercury Sable ProblemsEngine Stalling and/or Hesitation on Acceleration due to Faulty Idle Air Bypass Valve
If you experience difficulty starting the engine when cold, stalling at idle, or hesitations during acceleration, it may be the idle air bypass valve. This valve helps the vehicle idle steady when the accelerator pedal is not pressed.
The engine oil pan gasket can develop a leak. Leaking oil may accumulate on the exhaust system resulting in a burning smell. Replacing the gasket should correct this leak.
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.

1991 Mercury Sable RecallsFord Recalls 1986-1995 Vehicles for Corroded Subframe Mount Plate Nuts
Ford has recalled certain 1986-1995 Taurus and Mercury Sable models and 1988-1994 Lincoln Continental models in high corrosion, cold weather states because the rear subframe mount plate nuts may corrode and fail, causing the subframe to drop. If the subframe drops, loss of vehicle control and functionality can occur. Dealers will install subframe rear mount bolts, reinforcement plates, and plate nuts.
Ford has recalled certain 1991-1995 Taurus and Mercury Sable models equipped with the 3.8L V6 and 1991-1994 Continental models for an issue with the speed control cable. In cold weather states, the speed control cable could freeze. This could cause the accelerator cable to stick. To deter moisture and ice build-up, dealers will add a rubber boot to the speed control cable.
Monroe has recalled certain 1990-1994 Taurus and Mercury Sable vehicles with Monroe aftermarket struts installed for a concern with the weld mounting on the sway bar bracket where it attaches to the strut tube. On some vehicles, this weld did not fuse properly, which can cause the sway bar to drop and possibly contact the tire, damaging it. Monroe dealers will replace the affected struts.
