Ford Explorer engine vibrations when accelerating slowly or backing out on Ford Explorer

Some Ford Explorer owners report experiencing engine vibrations during slow acceleration or while backing out, which may be caused by several factors. A bad or dirty air filter can restrict airflow, leading to vibrations under acceleration. Additionally, clogged fuel lines may result in insufficient fuel supply to the engine, contributing to the problem. Spark plugs are also a potential source of engine vibrations, particularly during acceleration. Some owners of Ford Explorers with a 2.3L engine have noted vibration or rough idle in DRIVE or REVERSE, as well as a lack of engine RPM and shuddering while driving. Furthermore, hesitation during acceleration can arise from issues with spark plugs and the ignition system. In some cases, vibrations may indicate problems with the axles, especially in certain models like the 3.5L Ford Explorer. To resolve these issues, it is advisable to inspect and potentially replace the air filter, clean the fuel lines, check the spark plugs, and evaluate the condition of the axles. If problems persist, consulting a mechanic or dealership for a thorough diagnosis and repair is recommended.
