Ford Ranger engine sputters and shuts off while driving after throttle position sensor replacement on Ford Ranger

Some Ford Ranger owners report experiencing engine sputtering and shutdowns while driving after replacing the throttle position sensor. This issue may stem from a faulty new throttle position sensor, leading to erratic engine behavior. Additionally, fuel pressure problems can arise if the pressure after the high-pressure fuel pump is unstable. Ignition system issues, such as bad spark plugs or malfunctioning crank and cam sensors, can also contribute to sputtering and stalling. Furthermore, insufficient fuel delivery due to clogged fuel injectors or a failing fuel pump may result in similar symptoms. Electrical problems, including faulty wiring or connections, can cause intermittent sputtering and shutdowns as well. Lastly, concerns with the engine control module (ECM), which relies on input from the throttle position sensor, can lead to performance issues. To effectively address these problems, it is crucial for owners to diagnose the throttle position sensor, check the fuel system, inspect the ignition system, and consult a qualified mechanic if the issues persist.
