Buick LaCrosse car shakes and does not accelerate after stopping on Buick LaCrosse

Some Buick LaCrosse owners report experiencing shaking at idle, which may be attributed to misfiring cylinders, bad motor mounts, or engine damage. Additionally, some owners encounter issues with acceleration after stopping, potentially caused by a lack of air, fuel, or proper ignition, with common culprits including a clogged air filter, faulty fuel pump, malfunctioning throttle position sensor, or a clogged catalytic converter. Furthermore, slow acceleration has been linked to problems such as a dirty mass air flow sensor, clogged fuel filter, fuel pump malfunction, faulty oxygen sensor, dirty throttle body, worn spark plugs, or a clogged catalytic converter.
