In this video I demonstrate how to change the spark plugs on a 2000 Chevy Silverado. The process may be a little different from car to car but the main idea should be the same. If you have a distributor make sure that you have the wires going to the correct plugs. For all Chevy LS V8 the process should be very similar. If you are trying to diagnose poor performance, rough idle, or similar issues, I would try changing the plugs to see if it helps.
