    Q:
    What should you do if replacement of Spark Plug Wires is necessary for the 2012 GMC Sierra? Posted by Hunner L.
    A:
    If replacement is necessary, obtain a new set tailored to your engine model, and replace the wires one at a time to avoid firing order mix-ups. Pay close attention to the wire routing, and on V6 engines, release the ignition wire loom clamps to swap the wires before securing the clamps onto the new wires.
