Solving the P0354 Code in Your Ford F150 5.4 Engine

P0354 is a diagnostic trouble code (DTC) for the Ford F150 5.4 engine. This code indicates that the engine has detected a misfire within one of its cylinders. A misfire occurs when a cylinder is not firing as it should, resulting in incomplete combustion and inefficient operation of the engine. Symptoms of this code are often noticeable with a decrease in power and fuel economy, as well as rough idle and hesitation when accelerating. To resolve this issue, a thorough diagnosis of the misfiring cylinder must be performed to identify and repair any underlying problems that may be causing the misfire.
