1991 Cadillac Fleetwood Problems
Brake fluid can become dirty and may cause problems in the brake system; it should be flushed every 60,000 miles.
The spark plugs should be replaced every 30,000 miles and the spark plug boots should be checked for hot spots and cracks.
The engine control module (ECM) electrical grounds on the front of the engine block may have high resistance causing a rough running engine or stalling condition.
Excessive carbon build up in the engine combustion chambers may be the cause of a smog check failure due to excess NOx emissions. A "top engine" decoarbonization cleaning procedure will commonly correct this concern.

1991 Cadillac Fleetwood Reviews
I'm riding a fleetwood 91 for 6 years now and still love it like the first day, with more than 400000 km the engine is still running smouth and strong, and never failed starting even at -40c (im living in Montreal,Canada).And those who cares about fuel economy, for it is a V8 4.9l engine it's swolowing 11 L/100km on free-way (at 100kmh) and around 14 L/100km in town, considering the high millage it's a good score.
