1990 Lincoln Mark VII Problems

Incorrect starter relay can cause poor running/low fuel economy
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.
Overheating Due to a Damaged Impeller

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.

 

Problems With EGR System are Common in High Dust Areas

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.
