Acura TSX ignition coil failure causing intermittent cylinder misfire and rough running issues on Acura TSX

Some Acura TSX owners report experiencing ignition coil failure, which can lead to intermittent cylinder misfires and rough running issues. Common signs of this problem include engine hesitation during acceleration, rough idle, misfires, excessive fuel consumption, and the illumination of the check engine light. Specifically, misfires in cylinder 1 may be caused by faulty spark plugs and coils, triggering trouble codes such as P0301 and P0302, which indicate misfiring and can threaten the vehicle's drivability. Additionally, symptoms often include noticeable rough running at idle and misfiring in specific cylinders. Owners are advised to diagnose potential ignition coil issues promptly, especially if the check engine light is flashing, to prevent further complications and ensure optimal vehicle performance.
