How do you change spark plugs on a 2006 Impala LTZ?
i think either you skipped a digit in what you typed or you are trying to replace the plugs very prematurely. the plugs in moist newer cars are not due to be replaced until 75000-100,000 miles. if you insist on replacing them still, locate the coil packs, remove them, and the plugs should be just below that .
