Question about 1998 Buick LeSabre
Chris, these cars are notorious for misfires.
The coils may be firing but often they will leak the spark off a cracked tower or internally.
Also check each spark plug carefully for carbon tracks on the outside of the porcelain insulator.
These carbon tracks are caused by repeated ignition sparks traveling down the outside of the spark plug. This is what I see most of the time on these cars.
If you see this, replace the plug that is tracked and the ignition wire as well.
Use di-electric grease on the inside of the new wires to help prevent tracking on the new wires.
This advise should lead you to repairing your misfire.
Thank you for using FixYa.
