Most reported 1991 Lincoln Continental problems

In high dust areas, problems with the EGR system are common. The filter for the EGR solenoid may plug and cause the EGR to activate when it should not; this can cause the engine to stall. The dirty filter should be replaced to correct this concern.

An exhaust leak may develop in front of the catalytic converter. This type of leak should be corrected as soon a possible to avoid damaging the catalytic converter.

Erratic engine coolant temperature or intermittent overheating can be caused by corrosion inside the water pump. The impeller may spin on the water pump shaft or the impeller may corrode. Either condition reduces coolant circulation resulting in engine overheating.

Check the battery cable ends frequently for corrosion. Corrosion can easily migrate under the cable insulation and cause numerous electrical faults and drivability issues.

Checking and adjusting the AC compressor clutch air gap can extend the service life of the AC compressor.

There were problems with premature head gasket failure that could cause overheating problems due to coolant loss. A new head gasket design and assembly procedure was released to fix the problem.

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.
