how to replace spark plugs wires 1992 buick century v 6 3300 stationwagon

Replace the spark plugs.
Answer is No, I just tried having a 92 and 93 ls 400. Plugs are different and dash config is different.
Its easy, remopve the covwers on top of the valve covers. Only two bolts hold them on. The covers are black, and read "V8 4-Cam" on the rights side one. Under these covers are the boots for the plug wires, remove one by one and the spark plugs are underneith. remember to change when the engine is cool and good luck

A person can replace the rear spark plugs very easily. Disconnect the battery, remove the cables/boots and the old spark plugs. Put in the new spark plugs, reconnect the cables and boots, and reconnect the battery.
