Ford Expedition misfire during rapid acceleration, possible throttle position sensor issue on Ford Expedition

Some Ford Expedition owners report experiencing misfires during rapid acceleration, which may be attributed to a faulty throttle position sensor. This malfunction can lead to poor fuel economy and relay inaccurate data to the vehicle's computer. Symptoms of a defective throttle position sensor include engine misfires, stalling, rough idling, and an unresponsive throttle. Additionally, misfires during acceleration, particularly uphill or at high RPM, are often indicative of throttle position sensor issues. Overheating conditions can further impact the throttle system, necessitating attention to coolant levels or engine temperature readings. Common causes of throttle position sensor failure among owners include electrical issues such as corroded connections, damaged wiring harnesses, or short circuits disrupting sensor signals. It is advisable for owners experiencing these symptoms to have the throttle position sensor checked and potentially replaced to effectively address the issue.
