How do you replace spark plug wires on 1999 camry?
Very simple to do. Purchase 4 new platinum spark plugs for the vehicle. You will need a spark plug socket (it has rubber on it to grip the spark plug you are taking out) and an extension of at least 8 inches. When you open the hood you will see the 4 spark plug leads on top of the engine. Unplug the leads ….put the spark plug socket down each hole and unscrew the spark plugs. The new spark plugs will likely be already gapped to the .043 inches needed. Screw the sparks plug in (I made sure I did not put the spark plug socket on the spark plug too tightly or you could leave the spark plug in the socket hole.
