You will need to raise the front of vehicle off ground, remove the front wheels and any shields in place. You may also need to reach a few of the spark plugs from under the vehicle. The Camaro was equipped with a 3800 series II engine, which is not the same as the original 3800. The original 3800 is a front wheel drive engine, whereas the series II is rear wheel. It may take some time to replace your plugs, but with patience, it can be done.
