1990 Buick Century Problems
RepairPal has identified the most common problems with the 1990 Buick Century based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
Fuel injectors can short-circuit electrically causing a rougher than normal idle and reduced performance.
A ticking noise may develop from the engine due to a cracked exhaust manifold. Damaged exhaust manifolds will require replacement to correct this issue.
The torque converter clutch can stick "on" after extended freeway driving causing the engine to stall when coming to a stop. Our technicians tell us when this occurs, the engine usually will restart and stall when put into gear. After allowing about twenty minutes for the engine and transmission to cool down, the engine will start and the transmission will operate normally. Replacing the torque converter clutch solenoid, transmission filter, and fluid will generally correct this issue.
