Q: How to check and replace spark plugs for the Honda Del Sol?
A: It is necessary to use a spark plug socket, wire-type feeler gauge, and torque wrench when replacing spark plugs. You should purchase the correct ones for your automobile, adjust the gap, and change one at a time. Check electrode gaps, if necessary correct them. To avoid mixing up wires, remove and replace only one spark plug at a time. The anti-seize compound should be used on the threads so that they do not seize. Use 3/8-inch ID rubber hose to align the plug with the hole. Attach a new plug by repeating procedure for all plugs.
