Customer Question

2011 Silverado Hybrid.
Started running REALLY rough on the way home. Took it to get quick diagnostic, said cylinder #7 misfire.
Bought plugs, wires, and a cool, replaced cylinder #7 plug and wire. Took for a test drive around the block. Still doing it, and was WAY WORSE in reverse.
WTF???
