For a 1990 Buick Century V6 3.3L engine, the manufacturer's recommended spark plug gap is .060" (1.52mm)
On a 1990 Buick Electra Park Avenue, the spark plug wires connect to the ignition coil pack and the spark plugs themselves. The ignition coil pack is typically located on the engine, and each wire should be routed to its corresponding spark plug in the order specified by the firing sequence. Ensure that the wires are connected securely and routed away from any hot surfaces or moving parts to avoid damage. Always consult the vehicle’s manual for the correct firing order and specific wire routing.
Just drive it until it falls off, since it's its 1990 Buick. jk, i really dont know.
