1991 Lincoln Mark VII Problems

Engine -- Verified

If you experience poor running and low fuel economy after the starter has been repaired, it could indicate that an incorrect starter relay was used. A diode-suppressed starter relay may be needed.

Engine -- Verified

To extend fuel pump life, replace the fuel filter more often than the manufacturer recommends.

Engine -- Verified

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.
 

Exhaust & Emissions -- Verified

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.

Exhaust & Emissions -- Verified

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.
