1991 Buick Century Problems
The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.
One or more power window switch may fail. The affected window may work intermittently before failing completely.
The transmission pressure control solenoid may fail causing erratic shifting. Our technicians tell us that partial dis-assembly of the transmission is necessary to replace a failed pressure control solenoid.

An excellent car for those who like to explore while being comfortable. Also great as a commuter vehicle because of the fact that one has plenty of legroom and trunk space is not limited.
