SOURCE: Buick Lesabre 1998, How you check the coil packs?

you can take them off and have them tested or you can pull the plugs and there should be two plugs that will be really black follow those wires back to the coil that is bad. or you could also have someone crank it while you stick a screwdriver in the end of the wire on the plug and hold the screwdriver next to the engine or a good ground and there should be a bright blue spark but be careful and dont touch the car or it might tickle a little bit

SOURCE: KNOCK SENSOR

When a knock is detected, it sends this information to the computor, in which retards the ignition timing. If the sensor is bad, it will do this more often than not.

SOURCE: 2004 Buick Lesabre uses quart of oil in 3K miles. Is this normal?

No it's not have your engine check for oil leaks, also have then do a wet and dry cylinder compression test this will let you know if you are burning oil, also have them check the spark plug's.Hope this was helpful.

I have a 2004 Buick LeSabre. My dashboard lights have been flickering on and off and now they are completely out. This only happens during the daytime. At night or if I go into a parking garage where it...


It sounds like they are automatic lights and that the light sensor is going bad. Look around on the dashboard for a small plastic dome, that is where the sensor is. There should be a plate or something holding it in place.
