  Q: How to spark plug replacement for Pontiac Fiero?

  A: For spark plug replacement, use a spark plug socket with a rubber grommet on the inside for protection of the porcelain insulator and also for holding the spark plug when it is being led to the hole where it is supposed to be inserted. With this type of gauge, one should check and adjust its gaps through inserting it between the electrodes. Check new plugs for defects and use a wire-type gauge to check the electrode gaps. In case of need, correct it by bending the side electrode. Align them. For you not to mess up with wires, make sure that you work with only one spark plug at a time. Utilize pressurized air or bicycle pump so as to clear off debris from around the spark plugs. After removing an old spark plug, compare it with others in order to assess your engine's condition. A small piece of rubber tubing will help you prevent cross threading by aligning the hole with a plug. Use twisting motion when attaching a spark plug wire. Repeat this process for other plugs.
