Your Lesabre motor creates a spark to burn the fuel and air mixture, and then sends exhaust through the mufflers. The ECM makes sure these functions are done efficiently. When your ECM fails, your Buick starts and runs poorly. A new Buick Lesabre engine control module from AutoZone restores smooth driving. Buy your Century engine control computer online and get Free Shipping on $75 or more. Need it today? Select Same Day Store Pickup (in most cases). While you're at AutoZone, ask our helpful staff about other items to keep your Buick Lesabre running and looking perfectly.
