1990 Mercury Sable Problems
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.
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.
White smoke coming from the exhaust could indicate that a head gasket has blown or there is a cracked cylinder head. Our technicians tell us that removal and inspection of the cylinder heads will be required to confirm a crack is present.

1990 Mercury Sable Recalls
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.
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.
Ford has recalled certain 1990 Taurus and Mercury Sable and 1991 Explorer vehicles for an issue with the front seat rigid seat belt buckles. Some buckles will not release, some will not latch at all, and some may not latch fully. All concerns pose safety risks to occupants. Dealers will replace the rigid mounted belt buckles with end release buckles.
