Chevrolet Tahoe shaking issue with engine light on, possible engine replacement needed on Chevrolet Tahoe

Some Chevrolet Tahoe owners report experiencing shaking issues accompanied by an illuminated engine light, which may be linked to several potential causes. These owners often find that deteriorating spark plugs can lead to vibrations while idling or accelerating. Additionally, a flashing check engine light is reported as a sign of severe engine problems that should not be ignored, as it can result in more significant issues if left unaddressed. Faulty ignition coils are also noted as a common cause of engine performance problems and can trigger the check engine light. Furthermore, lifter failures in both the 5.3-liter and 6.2-liter V8 engines are reported to cause shaking and rough idling. It is advised that owners conduct regular maintenance, such as checking and replacing spark plugs and ignition coils, to potentially resolve these issues without resorting to an engine replacement. For those uncertain about the cause, consulting a certified Chevrolet mechanic is recommended for accurate diagnosis and appropriate solutions.
