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.

Sounds more like you have a bad fuel pump.If you have a pressure tester then check the fuel pressure.You need top have between 41-47 psi fuel pressure.

    One high beam not working 2006 Buick lacrosse


    Sampson, sounds like a bunt out bulb, which will need changed.
    If you feel comfortable doing it yourself. Basically three screws, and you have to pull one plastic fastener from the fascia (bumper) and pull the bumper back a bit, and pull the assembly out. I believe it is in the manual, not bad to do. I will post a link to tell or show you how to do it. Press the helpful button
