To fix a 2000 Ford Windstar SE from pinging on acceleration, start by checking the fuel quality and ensuring you're using the recommended octane rating. Inspect and clean the spark plugs and ignition system, as faulty components can contribute to pinging. Additionally, check the timing and adjust it if necessary, as improper timing can lead to pre-ignition. If the problem persists, consider testing the engine for vacuum leaks or issues with the fuel system, such as a clogged fuel filter.
