I've experienced acceleration issues several times while driving my Buick Regal, where stepping on the gas pedal had no response, as if the car was having spasms. Common causes include fuel system malfunctions, such as an aging fuel pump failing to supply sufficient fuel, or poor-quality fuel in the tank clogging the fuel injectors; a clogged air filter affecting air intake and causing the engine to lose power; or worn-out spark plugs leading to poor ignition and stuttering during acceleration. There are also electronic components like the throttle pedal sensor failing, sending incorrect feedback signals. Once, I fixed the problem simply by replacing the air filter myself—quick and easy. But for more serious issues, repairs are necessary; otherwise, it can be dangerous, especially when overtaking on the highway. Addressing problems early is the safest approach. Regular maintenance can prevent these issues.

Having worked on cars for years, a Buick Regal's inability to accelerate may be caused by insufficient fuel pressure—check if the fuel pump is functioning properly; a blocked intake system, such as a dirty air filter or a leaking intake pipe; ignition system failures like worn spark plugs or faulty ignition coils; transmission issues like slipping that also affect acceleration; or electronic control system faults such as sensor or ECU malfunctions leading to signal misreading. I suggest the owner first perform a self-check to see if the air filter is clean and whether any warning lights are on. If the issue persists, visit a professional shop to test fuel pressure and sensor readings with proper tools. Safety first—don’t force the car to run.

As a commuter driver, it's particularly frustrating when my Buick Regal can't accelerate properly, making me feel unsafe. It could be due to a clogged fuel system or faulty electronic components, such as a dirty throttle body causing poor air intake. I once had a similar issue, and sending it for fuel system cleaning fixed the problem. I recommend paying close attention to changes in engine sounds; if you notice a lack of power during acceleration, stop and check immediately. Wait for professional repair and avoid tampering. Safety is always the top priority, and regular maintenance can save a lot of trouble.
