ok...i have never actually done a spark plug change on a 3800 motor...but i do know that you some how have to "rock" or "tilt" the entire forward to get to the 3 plugs in the rear...ive heard that you car put the car in park and rock the car...or removing the dog bones and using rachet tie downs will tip it forward
first you need to state what liter the engine is.
60 thousandths is the correct gap on platinum tipped plugs
the spark plugs are located on the front of the engine under the hood
from underneath the car you can get right to them
plugs wires
Check
Remove the spark plugs wire and remove the plugs wit a spaerk plug wrench or socket.
I own a 1996 Buick Riviera and the check engine light started flashing.I noticed a slight loss in acceleration.Could this be bad gas,a clogged fuel filter,or the spark plugs and wires may need changing.Help me.

After alot of time and searching it has come up with a 1993 buick la sabre has a total of four freeze plugs on it and are very easy to get to and change.
I suggest you install OEM AC/Delco plugs.
