What Causes the Buick GL8 to Have Weak and Stuffy Acceleration?
2 Answers
Buick GL8 experiencing weak and stuffy acceleration may be due to abnormal engine acceleration, possibly related to fuel system issues such as the fuel pump or fuel injectors. It could also be caused by ignition system problems, such as spark plugs or ignition coils. Under normal circumstances, pressing the accelerator pedal increases the engine's RPM, thereby enhancing the output power, which in turn increases the vehicle's speed.

I've been driving a Buick GL8 for almost two years, and recently experienced a lack of power during acceleration—it felt like the car was holding its breath and struggling. There can be various reasons for this, but the most common is an underperforming fuel system, such as a clogged fuel filter or an aging fuel pump, which prevents gasoline from reaching the engine efficiently. If there's an issue with the ignition system, like worn spark plugs or faulty ignition coils, incomplete combustion can also lead to that sluggish feeling. On the air intake side, a clogged air filter can suffocate the engine, making acceleration sluggish. Sensor malfunctions, such as an inaccurate oxygen sensor reading, can affect throttle response. For the exhaust system, a blocked catalytic converter can trap exhaust gases, causing the car to feel stifled. From my daily driving experience, I've learned that regularly replacing filters is crucial to prevent dust buildup. Loss of acceleration isn't a minor issue—it can compromise highway safety—so it's best to visit a 4S shop promptly for a computer diagnostic to avoid minor issues turning into major repairs.
